Metsorsquos mobile crushing and screening units are in the frontline in the demandingreconstruction efforts in Japan after the nation was ravaged by the biggest earthquakeand tsunami in its recorded history Tracked mobile Lokotracks are the quickest wayto boost the production of aggregates an estimated 200 million tons of which willbe required over the next decadeTEXT amp PHOTOS Eero Haumlmaumllaumlinen
The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

Endomines
Pampalondash a green andresponsiblegold mineAt Pampalo near the easternmost point of Finland a cleanand environmentally friendly gold mining operation isbeing executed by Endomines With Metsorsquos plant designand a state-of-the-art processing plant Pampalo runs a
green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines
originally founded in Sweden
According to Ekberg the strategy when
building the mine was to split up the jobsinto small separate contracts Metsorsquos part
was the main minerals processing system gt

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

Pampalondash a green andresponsiblegold mineAt Pampalo near the easternmost point of Finland a cleanand environmentally friendly gold mining operation isbeing executed by Endomines With Metsorsquos plant designand a state-of-the-art processing plant Pampalo runs a
green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines
originally founded in Sweden
According to Ekberg the strategy when
building the mine was to split up the jobsinto small separate contracts Metsorsquos part
was the main minerals processing system gt

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

According to Mine Manager Tom Soumlder-
man the known gold ore reserves at the
Laiva gold mine amount to 169 million
tons but the potential for additional find-
ings looks good
ldquoWorking at the level of two million tonsper year our expected lifetime is about nine

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its
first mining rights at Laiva

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used

Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment
for this project as it washes the sand thatMr Sunil Tyagi Deputy Project ManagerAFCONS-Strabag

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

Endomines
Pampalondash a green andresponsiblegold mineAt Pampalo near the easternmost point of Finland a cleanand environmentally friendly gold mining operation isbeing executed by Endomines With Metsorsquos plant designand a state-of-the-art processing plant Pampalo runs a
green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines
originally founded in Sweden
According to Ekberg the strategy when
building the mine was to split up the jobsinto small separate contracts Metsorsquos part
was the main minerals processing system gt

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is
yet another mining hotbed thatrsquos going to

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

Active exploration drilling going on
According to Mine Manager Tom Soumlder-
man the known gold ore reserves at the
Laiva gold mine amount to 169 million
tons but the potential for additional find-
ings looks good
ldquoWorking at the level of two million tonsper year our expected lifetime is about nine
years We carry out active exploration drill-
ing in Kaukainen Musunneva and Oltava
to locate nearby satellite ore bodies Anupdated detailed mine life plan will be pre-
pared during the autumnrdquo Soumlderman saysNordic Minesrsquo other exploration areas

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

Pampalondash a green andresponsiblegold mineAt Pampalo near the easternmost point of Finland a cleanand environmentally friendly gold mining operation isbeing executed by Endomines With Metsorsquos plant designand a state-of-the-art processing plant Pampalo runs a
green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines
originally founded in Sweden
According to Ekberg the strategy when
building the mine was to split up the jobsinto small separate contracts Metsorsquos part
was the main minerals processing system gt

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso

company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship

mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Following the acquisition of
the HP200 Areia amp Cia is now
also producing special sands
that command a price that is100 higher than common
sand The entire stockpile of
pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms
the transformation that has taken place in
the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

wouldnrsquot have worked for us in the stipu-lated timerdquo Mr Tyagi adds
When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

local market to use in concrete surfacingprefabrication etcrdquo
Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The biggest gold producer in Europe
Agnico Eagle in Kittilauml Northern Finlandcurrently produces some 5000 kg of goldannually The mine plans to expand its daily
ore extracting capacity to 4000 metric
tons which will increase the gold produc-
tion by an additional 1000 kgOther major gold producers in Fin-
land include Nordic Minesrsquo Laiva mine
Endominesrsquo Pampalo mine Lappland
Goldminersrsquo Pahtavaara mine and DragonMiningrsquos Orivesi and Jokisivu mines
Metso with its crushing screening and
minerals processing equipment is a sup-
plier to most Finnish gold mines In addi-tion to the equipment Metso also offers
these gold-mining operations its process
planning expertise and services
New gold deposit discoveries likely
Senior Geoscientist Pasi Eilu from the Geo-
logical Survey of Finland believes that the
possibilities of finding new gold deposits
comparable to the current ones are good
Helping Japan to rebuild
after the tsunami
ldquoIn Finland gold has been found
wherever serious exploration has beencarried out The latest interesting depositshave been located by Mawson Resources
between Tervola and Ylitornio in Northern
Finlandrdquo
According to Eilu the latest findings onlyinclude gold ore exposed at the surface
ldquoIt is very likely that in the near future
gold will be found in the deposits hidden
completely undergroundrdquo he explains ldquoNextyear the Geological Survey of Finland will
publish an estimate on possible gold depos-
its reaching a depth of one kilometer from
the surface This will provide more accurateinformation on potential discoveriesrdquo
The average gold grade in Finnish gold
mines is similar to any gold mine abroad
ldquoThe most common type in Finlandis orogenic gold ore which is similar to
nearly all ores originating in West Austral-
ian and Ontario Canada We also have
volcanic-related gold deposits for example
in the Orivesi mine and small amounts of
gold deposits similar to those found in the
worldrsquos biggest deposits in WitatersrandSouth Africardquo Eilu adds
Focus on green mining
The Finnish Green Mining concept is the
mineral sectorrsquos answer to future chal-
lenges It aims to optimize material and
energy efficiency in the whole productionchain The program aims at efficient pros-
pecting for new deposits and at develop-
ing new solutions for utilizing them It
also aims to minimize local environmentalimpacts and problems to improve work
safety and the workplace atmosphere andto restore mining areas after mining opera-
tions are completed The Green Mining program started in
2011 The main objective is to make Finland
a global leader in the sustainable mineral
industry by 2020 The program encom-
passes two central themes intelligentminimum-impact mines and new mineral
resources
NorthernEldorado Today Finland together with the Nordic countriesfalls within one of the global areas that are experi-encing a gold exploration and mining boomIn recent years major global mining companieshave entered the country and opened gold mines
and they are now set to expand their on-goingoperations A number of promising explorationprojects are simultaneously under way on behalfof some 40 mining companiesTEXT Eero Haumlmaumllaumlinen PHOTO iStockphoto

Pampalondash a green andresponsiblegold mineAt Pampalo near the easternmost point of Finland a cleanand environmentally friendly gold mining operation isbeing executed by Endomines With Metsorsquos plant designand a state-of-the-art processing plant Pampalo runs a
green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines
originally founded in Sweden
According to Ekberg the strategy when
building the mine was to split up the jobsinto small separate contracts Metsorsquos part
was the main minerals processing system gt

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

ldquoIn the eight months since the contract
came into effect our corporation has notsuffered any financial losses due to equip-
ment breakdown The regular maintenance
has greatly improved the efficiency of our
entire crushing system In addition the
experienced engineers from Metso also
provided onsite training and guidancefor our staff and the tailored training has
greatly enhanced the operating abilities of
our employees and upgraded their overalllevel of competencerdquo says Shen Yidong
More productivity with
less consumption
Metsorsquos service contract focuses on real-
izing the optimum performance of each

production system Metsorsquos techniciansproposed an adjustment to the closed side
setting of the HP500 for tertiary crushingin order to improve the efficiency of the
downstream fine crushing and milling pro-
cessing by over 10ldquoThe process flow improvement solu-
tions provided by Metso not only increased
the output of our gold concentrates but
also reduced our energy consumption andcostsrdquo says Shen
In the past wear parts procurement
took up a larger proportion of Zhongjiarsquos
total production costsldquoTo avoid downtime caused by the
shortage of wear parts we had to keepeight sets of various wear parts in place
However the cost of having so many wear

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product

tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-

discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for

handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle

unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

green and responsible yet at the same time profitablegold mining operation that avoids acid mine drainagesand targets 100 water recirculationTEXT amp PHOTOS Eero Haumlmaumllaumlinen
With a modest investment of EUR 20
million the Pampalo mine was built fully
operational and now produces 800ndash900 kgof pure gold annually An on-going expan-
sion will increase the minersquos production
capacity by 30 to 50 next yearIn addition to the main underground
mine at Pampalo several promising satellite
gold deposits are being investigated along
the long Karelian gold line The maximum
distance of the satellites is 30 km allowingthe mine to transport and process all of the
produced ore at the Pampalo plant
Small scale can be successful
with hard work
ldquoWith our gold mining operation we can
very well show that with hard work even
small-scale gold mining and production
can be done in a sound and profitable wayrdquosays Markus Ekberg CEO of Endomines

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

According to Mine Manager Tom Soumlder-
man the known gold ore reserves at the
Laiva gold mine amount to 169 million
tons but the potential for additional find-
ings looks good
ldquoWorking at the level of two million tonsper year our expected lifetime is about nine
years We carry out active exploration drill-
ing in Kaukainen Musunneva and Oltava

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-

beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment
for this project as it washes the sand thatMr Sunil Tyagi Deputy Project ManagerAFCONS-Strabag

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product

tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-

discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Increasing capacity makes processing
of lower grades economical
The project to significantly increase the
processing capacity at Pampalo is well
under way with the installation of for
example a second grinding mill and more
flotation cells The expansion will be in
operation during early 2013ldquoThe added capacity also makes it pos-
sible to economically process the nearby
open pits with a lower gold grade In addi-tion it helps us to optimize the crushing
and grinding circuitsrdquo Ekberg concludes
Active exploration drillings have
exposed new mineralized zones furtherextending the lifetime of the Pampalo mine
from the present estimate of 6ndash7 years

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

According to Mine Manager Tom Soumlder-
man the known gold ore reserves at the
Laiva gold mine amount to 169 million
tons but the potential for additional find-
ings looks good
ldquoWorking at the level of two million tonsper year our expected lifetime is about nine
years We carry out active exploration drill-

gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During
the same year the company purchased its
first mining rights at Laiva

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

also producing special sands
that command a price that is100 higher than common
sand The entire stockpile of
pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms

the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship

ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms
the transformation that has taken place in
the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Just one year after starting the gold recov-
ery process Nordic Mines is on track toreaching a capacity of 5 kg of gold per day
At present the operations are averaging 3
to 4 kg of gold daily
The ore in the Laiva Gold Mine consists
of packages of gold-bearing quartz-filled
shear structures The deposit is more thana kilometer long and 700 meters wide The
total depth is still unknown but dr illings
carried out thus far have shown gold-bear-ing shear structures 300 meters below the
surface
A typical ore zone includes a large num-
ber of thin shear structures from 5 to 30per meter The ore zones are commonly 50
to 100 meters long several are 10 meters
deep and they range from a few meters to
20 meters cross strike The minimum min-ing width is 25 meters which means that
even a minor ore zone consists of at least10 to 50 shear structures
Conventional pattern blasting
with selective loading
Prior to mining Nordic Mines conducts
grade control drilling which provides
dense gold grade information and makes
it possible to outline the boundaries
between ore and waste The mining
technique applied is conventional pattern
blasting with selective loading This is oneof the most commonly used techniques in
large-scale open-pit mining
A typical blast in the Laiva mine is 50
meters long 100 meters wide and 5 metersdeep After blasting ore and waste aremined by selective loading
After investing some EUR 100 million
the Laiva mine now comprises an open-pit
mine with a modern complete crushinggrinding and processing circuit that ends
with the casting of gold doreacute bars
With a number of mine staff partners
sub-suppliers city and state officials inattendance the Laiva gold mine was offi-
cially inaugurated on August 16 2012
Michael Nilsson Managing Director
of Nordic Mines stressed in his speechthe importance of overcoming challenges
during the building of the mine
ldquoObviously the whole development
took us longer than expected Today weare pleasantly surprised by the size of our
operation We are becoming much bigger
than expectedrdquo gt

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso

company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later
Nordic Mines with its sights set on
locating and exploiting gold in Swedenand Finland was founded in 2005 During

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day

and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is
yet another mining hotbed thatrsquos going to

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The story behind the discovery of the Laivamine is an interesting one During a hunt-
ing trip in the remote forests of Laivakan-
gas in 1979 Pentti Jaumlmbaumlck found an inter-esting-looking piece of stone Although hecould not see the gold hidden inside the
rock Pentti noticed the striking weight
and somewhat different look of the stone
Upon returning home Pentti sent thesample to Outokumpu which at the time
was the leading state-owned mining com-
pany in Finland After testing a high gold
content of 15 grams per ton was found
Gold deposit founded by a hunter
The founder of the Laiva gold deposit Mr Pentti
Jaumlmbaumlck was the guest of honor during theinauguration
Lennart Schoumlnning Chairman of the Board ofNordic Mines holding a gold doreacute bar worthsome EUR 320000
Outokumpu registered a mining claimon the area and conducted a series of
exploration drilling from 1981 to 1987 Due
to the low price level for gold no mine wasstarted at the time Other mining compa-nies such as Endomines held the mining
rights later

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes

between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

ldquoIn the eight months since the contract
came into effect our corporation has notsuffered any financial losses due to equip-
ment breakdown The regular maintenance
has greatly improved the efficiency of our
entire crushing system In addition the
experienced engineers from Metso also
provided onsite training and guidancefor our staff and the tailored training has
greatly enhanced the operating abilities of
our employees and upgraded their overalllevel of competencerdquo says Shen Yidong
More productivity with
less consumption
Metsorsquos service contract focuses on real-
izing the optimum performance of each

production system Metsorsquos techniciansproposed an adjustment to the closed side
setting of the HP500 for tertiary crushingin order to improve the efficiency of the
downstream fine crushing and milling pro-
cessing by over 10ldquoThe process flow improvement solu-
tions provided by Metso not only increased
the output of our gold concentrates but
also reduced our energy consumption andcostsrdquo says Shen
In the past wear parts procurement
took up a larger proportion of Zhongjiarsquos
total production costsldquoTo avoid downtime caused by the
shortage of wear parts we had to keepeight sets of various wear parts in place
However the cost of having so many wear

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Metsorsquos HRCtrade takes high pressure grinding roll technology to the next level
The new Lokotrack mobile conveyors come as tracked and wheeled models
Metsorsquos latest development in comminution equipment the HRCtradeis a major step in the profitable application of high-pressure grind-
ing roll (HPGR) technology Metso has made several key innova-
tions in order to increase throughput and decrease the total cost
of operation
Metsorsquos patented Arch frame creates an even gap setting acrossthe width of the tires limiting skewing that can result in downtime
for mining operations This anti-skewing Arch frame also prevents
damage to the roller bearings (caused by misalignment) that canoccur with the traditional HPGR design
Flanges maximize wear life and increase throughput
Used in place of spring-loaded cheek plates the flanges keep thebed of material within the crushing zone and prevent material
from bypassing the tires This enables greater circuit capacity and
increases the overall crushing efficiency
In addition by preventing material from bypassing the tires
even pressure across the width of the tire is better maintained
Distributing the pressure more evenly maximizes the tire life bypreventing a ldquobath tub effectrdquo in which the center of the tire wears
faster than the edgesVictoria Herman Metsorsquos Product Manager for the HRC notes
that this breakthrough design is a response to the growing needs
in the mining industry ldquoEnergy efficiency has been attracting our
customers to HPGR technology for yearsrdquo she says ldquoBut our design
concept increases capacity and crushing efficiency ndash and thatrsquossomething mining companies are always looking to improve onrdquo
The track-mounted Lokotrack CT32 and wheel-mounted Lokotrack
CW32 mobile conveyors offer an ideal solution for applications
that require high stockpile capacity and excellent material transfer
capabilities They also add flexibility to multi-stage crushing andscreening applications enabling easy and fast closed-circuit opera-
tion of mobile units
The conveyor novelties can be used in both mobile and station-
ary installations providing extra stockpiling capacity in situationswhere for example fewer wheel loaders are available
The HRC is ideal for high-tonnage hard rock applications andcan be used as a tertiary quaternary or pebble crusher Currently
several HRC units are in operation around the world ndash with a total
of 6500 operating hours including over 3800 hours in a mininghard rock application The machine does have range within hardrock applications itrsquos been designed for use in diamond iron ore
copper gold platinum and various industrial minerals

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best
partner for usrdquo Shen Yidong concludes

ldquoIn the eight months since the contract
came into effect our corporation has notsuffered any financial losses due to equip-
ment breakdown The regular maintenance
has greatly improved the efficiency of our
entire crushing system In addition the
experienced engineers from Metso also
provided onsite training and guidancefor our staff and the tailored training has
greatly enhanced the operating abilities of
our employees and upgraded their overalllevel of competencerdquo says Shen Yidong
More productivity with
less consumption
Metsorsquos service contract focuses on real-
izing the optimum performance of each

production system Metsorsquos techniciansproposed an adjustment to the closed side
setting of the HP500 for tertiary crushingin order to improve the efficiency of the
downstream fine crushing and milling pro-
cessing by over 10ldquoThe process flow improvement solu-
tions provided by Metso not only increased
the output of our gold concentrates but
also reduced our energy consumption andcostsrdquo says Shen
In the past wear parts procurement
took up a larger proportion of Zhongjiarsquos
total production costsldquoTo avoid downtime caused by the
shortage of wear parts we had to keepeight sets of various wear parts in place
However the cost of having so many wear

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen
Best partner
ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-
ucts and services Taking all aspects into
consideration we believe Metso is the best

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

and a procurement plan for wear parts
These really suit our needs perfectlyrdquo saysShen Yidong the Manager of ZhongjiaMining Industry
Effective preventive maintenanceFor mining corporations the biggestconcern is the economic losses caused by
the shutdown of equipment As a result
preventative maintenance is of vital impor-
tance During the contract period Metsoservice engineers offered 7-day tracking
service on the production site every month
to eliminate potential problems and thus
ensured the stability of the system
parts caused pressure on our working capi-tal which was not favorable for our long-
term developmentrdquo Shen explains
To solve this problem Metso designed
a rational stock plan of wear parts and built
a field warehouse In accordance with theuse and consumption of the liners the field
service engineers complement the stock tomake production and operations run more
smoothlyldquoNow when we need to replace the
wear parts we can use them before pay-
ment This not only simplifies the procure-
ment process but also liberates a largesum of our operating capital which can
be used for other business development
purposesrdquo says Shen

ldquoAlthough the LCS contract incurs some
early purchase costs in the long run Metsorsquosprofessional and quality service will improve
the equipment efficiency reduce ourenergy consumption and ensure stable
operations thus generating more prof-
its This is the greatest value for us so the
investment is really worthwhile overall Inthe future we will choose more Metso prod-

Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is
yet another mining hotbed thatrsquos going to

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso

company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine
Engineer Carlos Fernandez
ldquoWe hope to increase the total extrac-
tion of the three quarries from the present15 million tons per year because our plant
capacity allows more than double thatrdquo
Fernandez adds

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship

ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms
the transformation that has taken place in
the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Ofitas has pioneered the implementation
of several Metso novelties in the Spanish
market The company was the first to use
efficient large track-mounted Lokotrack jaw plants the unique mobile conveying
system and also the new-generation HP4
cone crushers
Today the company operates twomodern Metso stationary plants one in
Guadix near Granada and the newest one
in San Felices Haro Rioja community Both
quarries focus on refining hard rock by pro-cessing ophite rock into the highest quality
railway ballast asphalt and concrete mix
grades The company has a satellite quarry
near Vitoria in PentildeacerradaBeing situated next to a highway and
the famous Rioja vineyards Ofitas must pay
special attention to environmental issues
To minimize dust problems all conveyors
have special covers attached
Quality durability and service
The cooperation between Ofitas de San
Felices and Metso started back in 1973when the Ajuria family bought the com-
pany whose quarrying activities began in
1919 Intildeigo Ajuria has a clear vision of why
the cooperation has continued withoutinterruption for almost 40 years
long-standing personal relationshipsrdquoAjuria adds
Serving railways asphalt
and concrete producers
The year-old San Felices stationary instal-lation lies hidden in a mountainous area
south of the city of Vitoria in NorthernSpain The new plant replaces an old one
that complicated the extraction of ophiterock Both plants are delivered by Metso
With its two separate production lines
the new plant is able to produce all the
end products required ndash from railway bal-last to the finer grades needed for asphalt
and concrete
Due to lower demand the quarry cur-
rently produces some 4000 tons per day
At full capacity however the plant canreach 8000 tons of production per day
30ndash35 of which consists of railway ballastfor high-speed trains and 65ndash70 of chips
and sand Thanks to the versatile two-line con-
cept connected by transverse conveyors
up to 12 different end products can be pro-
duced Depending on the demand for endproducts the material can be guided either
to the HP4 cone or HP400 cone followed
by a Barmac vertical shaft impactor

Meeting the strictest cubicity demands
The Spanish regulations concerning end-product cubicity are becoming more
demanding The flakiness percentage of
railway ballast must be below 10 and for
asphalt and concrete aggregates less than
15
ldquoWith Metsorsquos HP4 cone and the Barmacvertical shaft impactor we can meet even
the strictest cubicity demands We believe
that our high quality is helping us to sur-vive in the present recessionrdquo notes Mine

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso

company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

sand The entire stockpile of
pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms

the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is
yet another mining hotbed thatrsquos going to
benefit from the companyrsquos support

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton

production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product

and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state
TEXT Deanna Lee PHOTO Metso
over the world ldquoWe are the first
company developing this kindof service in northwest Mexicordquo
adds Felix ldquoOur people have
developed a close relationship
with the team at the mine Itrsquosmore than a supplier relation-
ship our guys are inside the
mine living and working thererdquo
In fact this is the model
that Metso is using in servicehubs all over the globe build-
ing modern facilities bringing
teams on site and workinghand in hand with mine
operators The Cananea Service
hub is only the most recent
example of Metsorsquos commit-ment to service and northwest Mexico is

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

local market to use in concrete surfacingprefabrication etcrdquo
Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none
TEXT amp PHOTOS Monisha Majumdar
Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Following a large investment
in Metso crushing equipmentand services Buena Vista del
Cobre is now expanding the
mine site to include even more
equipment ndash and with thatexpansion comes the need for
more local service resources
Metso and Buena Vista del
Cobre have entered into a Life
Cycle Service agreement forthe plant and construction of a
brand new Metso service hub
is under way in Cananea
New facility new
level of service
The Cananea service hub
which will be up and running in early 2013will support the recent expansion and resur-
gence of Buena Vista del Cobre Initially it
will be a major repair and assembly center
for pumps crushers and screens and will
provide for rubber covering capabilitiesBut the 8000-square-meter facilityrsquos service
offering will be expansive including a con-
signment stock inventory to help serve theminersquos varying needs Metso currently has
50 service team members on site
Although Buena Vista del Cobre was a
key influencer in building the new servicehub this location will also enable Metso to
expand its capabilities and provide local
support to the entire mining community
in northwest Mexico The Cananea hub
will serve a number of major copper and
gold mines in the region including MineraFriscorsquos San Felipe Fresnillorsquos Milpillas and
Grupo Mexicorsquos Mexicana de Cobre
ldquoBuena Vista del Cobre is the biggestcustomer we have in Mexico today and
with this expansion project itrsquos only going
to grow and be strongerrdquo says Felix Forna-
guera Director of Services Mexico CentralAmerica and Caribbean ldquoWith that said the
idea behind the Cananea service hub is to
provide a central location for local support
for all our major customers in the areardquo
Establishing safety
ldquoIt was key to have our support here in
Cananea because the Buena Vista delCobre started from the ground uprdquo saysFelix ldquoWersquove been able to help the cus-
tomer to establish the best in support
service and operations from the very
beginningrdquo And this ground-up approachincluded a major focus on safety
Metso worked closely with Buena Vista
del Cobre to establish the safety proto-
col by which the mine operates Basedon Metsorsquos expertise the safety measures
put in place have enabled the mine to
become strict and efficient in its operations
and maintenance procedures To achievethis Metso worked closely with local andnational authorities to ensure the safety
plan was comprehensive and in accord-
ance with all established legal bodies
The best in regional support
The service hub in Cananea is a prime
example of Metsorsquos focus on providing local
service and support to its customers all
Service shines in Cananea MexicoAfter three years of inactivity the Buena Vista del Cobre mine in Cananea Sonora Mexico has been operational since 2010A mine that was inactive for such a significant amount of time however requires a great deal of support to successfullyrestart the plant and bring it back to an operational and profitable state

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

operations has already been

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

Sensitive projects require the best technol-

the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none
TEXT amp PHOTOS Monisha Majumdar
Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment
for this project as it washes the sand thatMr Sunil Tyagi Deputy Project ManagerAFCONS-Strabag

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

pebbles accumulated through-out the companyrsquos 20 years of
operations has already been
transformed into sand and the
stock of pebbles held by com-
petitors is also being purchasedfor processing
Cristiane Brizolari the
owner of Areia amp Cia confirms
the transformation that has taken place in
the production and commercial processldquoThe HP200 opened up new niches in
the market enabling the production of dif-
ferent types of sand with added valuerdquo

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

One of the biggest copper mines in
Europe Bolidenrsquos Aitik is located deep inthe wilderness of Swedish Lapland next to
the small town of Gaumlllivare The mine has
been operating since 1968 and a recent
expansion has increased its annual ore
production to 36 million tons
But the ambitious Swedes are not will-ing to lay back and relax just yet Bolidenrsquos
new aim is to reach a production rate of
45 million tons of ore per year in AitikAfter that Perhaps more than 55 million
tons The ore concentration in Aitik is very
low-grade with a mere 022 copper con-
tent hence the need for high capacityAchieving the ambitious production
goal requires maximum plant availability
This means that everything from the crush-
ers to the filters must be up and runningfor approximately 97 percent of the time
Thatrsquos where Metso comes into play
A cost-per-ton contract in action
The maximum uptime requirement allowsless than a dozen days per year for break-
downs repair and maintenance at Aitik
Every single hour during a service shut-
down counts There simply isnrsquot any roomfor surprises
Executing a successful shutdown under
such conditions requires a reliable service
partner not afraid of challenges and this iswhy Boliden has entrusted Aitikrsquos services
operations to Metso Boliden and Metsohave worked together since the 1960s
and the collaboration took another step
forward in September 2012 when the twocompanies signed a three-year extension
of the services contract for Boliden Aitik
ldquoThe new contract is a cost-per-ton
agreement We get paid based on Aitikrsquos
production Itrsquos a win-win deal for both par-
ties but also a new mindset for usrdquo explainsKurt Kalla Site Manager of Metso Gaumlllivare
Service Center responsible for serving Aitik
From now on the duration of the shut-down is what matters the most According
to Kalla the Metso service organization in
Gaumlllivare is now streamlining its operations
to fit the bill and has already witnessed thestrategy working In August 2012 Metso
carried out a 188-hour service shutdown in
Aitik which turned out to be a success
Zero tolerance for injury
One key factor to the success was theextensive planning of precautionary health
safety and environment procedures under-
taken by Metso prior to the shutdown Thanks to strict measures applied no
injuries or accidents occurred during the
shutdown and the work could easily be
finished on scheduleMats Johansson Health Safety
and Environment Manager for Metso in
Sweden explains how this was achieved
rdquoPlanning of the shutdown included arisk analysis for all new tasks participating
in Bolidenrsquos safety coordination meetingsmeeting with both Metso supervisors and
subcontractor supervisors and finally a
meeting with the entire staff participating
in the shutdown where everyone had to
sign a document stating their commitmentto the information providedrdquo he says
During the actual shutdown plenty of
new barriers signs and awareness cones
were put in place as a result of observa-tions from previous audits and safety plans
and risk analyses were readily available
in the work area Metso and Boliden also
introduced a Mill Inching permit a certifi-cate for completing a mandatory course for
those involved in the process In addition
Metso carried out random safety audits
during the shutdown to make sure thestrict policy was followed
According to Boliden Metsorsquos way of
working is a good example of how health
and safety precautions should be handled
ldquoMetso is a good example of how towork with safety and health plans risk
analysis permits and welding permits
Their table with all binders in the second-
ary mill area was exemplaryrdquo says Kjell-Arne
Johansson a technician from Boliden
The use of the new Metso Megalinertrade
system in the lining of Aitikrsquos Metso AG
mills has also improved the safety of main-tenance staff The Metso Megalinertrade con-
sists of larger-than-average liners bolted
in position from outside the mill Mainte-
nance technicians no longer need to go
inside the mill and stand in the dangerousdrop-zone of the liners gt
Boliden aims to reach a production rate of 45 million tons of ore per yearin the Aitik mine site
ldquoA complete risk analysis was conducted during the planningof the shutdownrdquo comments Mats Johansson Health Safetyand Environment Manager for Metso in Sweden

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none
TEXT amp PHOTOS Monisha Majumdar
Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to
conforms to the Indian standard for fines amp
coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

wouldnrsquot have worked for us in the stipu-lated timerdquo Mr Tyagi adds
When the going gets tough
partner with the toughest
Sensitive projects require the best technol-
ogy After AFCONS-Strabag landed theproject Metso was an obvious choice as a
technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

On the hook after theold C160 was liftedout by crane the newcrusher was installedin almost no timeOnly the roof of thehousing had to beremoved
sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Pebbles have always been a
challenge for producers of sandsince they cannot be returned
to rivers after extraction For
decades the processing of this
material resulted in a huge
environmental liability with alarge amount of pebbles hav-
ing to be stored away and left
unused
Transforming problems into
business opportunities
Areia amp Cia (areia = sand) has
operated in this market forover 20 years and decided to
enlist the help of Metso to find
a profitable solution for the
processing of pebbles
In July 2011 analyses werebegun to assess the abrasive-
ness and crushability of the
material Four alternatives wereidentified for processing and
transforming pebbles into sand
Initially Areia amp Cia was
interested in acquiring an
impactor for its reason-able price level However the
customer wanted to process
all the pebbles that were col-
lected daily in addition to some of the
material that it had stored In weighing theresults expected by the customer and the
excessive abrasiveness of the material the
HP200 cone crusher was decided on as thebest alternative
Areia amp Cia made the required invest-
ment and after using the HP200 for just
six months the company has already beenreporting outstanding results The HP200
not only transforms pebbles into sand but
also produces sand of excellent quality
with high yield and low maintenanceWith minor adjustments the HP200
also enables the production of sand withspecific particle size distribution for special
applications such as filtering sand blasting
and foundry sand adding value to the prod-
uct and increasing the types of sand offeredldquoMetso is pleased that the HP200 not
only enabled the processing of a product
that had been set aside as unusable but
HP200 cone transforms pebblesinto high-quality sandOver the last few decades Brazilian economic growth has been driving demand for construction aggregates The market
for sand in turn has been experiencing major difficulties in maintaining a consistent supply Presently one of the mainchallenges the industry faces is the large amount of pebbles that are obtained in the process of extracting sand at timesconstituting nearly 50 of the volume of material dredged from riverbeds

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than
800000 msup3 of rock will be moved Tunneling works started around spring
2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle

unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Where therersquos a will we dig a wayAFCONS-Strabag and Metso embark on tunnel project together
When the joint venture AFCONS-Strabag initiated work on the Rohtang bypass tunnel project at an altitude of 3980 metersabove sea level in Himachal Pradesh India they deliberated each aspect with clockwork precision The project involved anumber of surprises and challenges and required technology and project management skills that were second to none

Cutting a 10-meter-wide and nearly 9-kilo-
meter-long tunnel through the Himalayas
in one of the toughest terrains and cli-mates in India makes for quite a challengeResults set out to find out how AFCONS-
Strabag and Metso are making their way in
one of their most critical projects to date
The only road connection to the north-Indian border region of the province
Himachal-Pradesh and beyond the Manali-
Leh highway leads across the Rohtang
pass Due to the heavy snowfall and high-
velocity winds in this region the towns
located north of the pass are cut off from
the rest of the country during winter for atleast four often even six months each year
A tunnel with strategic importance
With the construction of the tunnel at
3100 m above sea level the Manali-Lehhighway will become an all-weather road
thereby enabling a significant improve-
ment in the economic development of
northern Himachal-Pradesh and an alter-
nate route to the strategically important
Ladakh region
Manali south of the pass is an alreadywell-developed tourist location that is
becoming more and more popular Upon
completion of the tunnel it is likely that
tourist activities will extend to the areanorth of the pass Moreover the tunnel
shortens the distance between the towns
of Manali and Leh by approximately 45 km
thus saving several hours on the small dan-gerous pass road
The Rohtang pass in the Western Himalaya
region of Northern India with its altitude ofalmost four kilometers ranks among thehighest trafficable passes in the world

The 88-km long horse-shoe-shaped
tunnel provides space for a two-lane8-m-wide carriageway as well as a one-
meter-wide footpath on both sides A
22-m-high and 36-m-wide emergency
tunnel will be integrated in the tun-
nel cross-section Altogether more than

2010 with excavation driven from both por-
tals As the north portal is inaccessible dur-ing winter closure the excavation focused
on the south After a planned construction
period of 55 years the tunnel is scheduled
to be completed by the end of 2015
Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-
uct quality and service deliverance Metso
strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Best man for the job
The BRO (Border Road Organization)
wanted to roll out a global tender for theproject due to the challenges that such a
project involves and also considering thatitrsquos the first time in India that a project of
this scale was to be carried out This imme-
diately triggered the need to roll out aglobal tender All major Indian construction
companies bid for it some individually and
some in partnerships
Strabag an Austrian tunnel specialistwas one of the companies who bid for the
project along with AFCONS a Mumbai-
based infrastructure company In Septem-
ber 2009 AFCONS-Strabag was awardedthe contract
Mr Sunil Tyagi Deputy Project Man-ager at AFCONS had this to say about the
unique projectldquoThis project is located in the Himalayas
and as far as we understand the terrain
there is among the toughest We came out
with a new technology and to be honestit is a fairly simple one We would generally
start with the traditional technology of drill-
ing and blasting and then obtain our muck
feed from the inwardbottom of the tunnelrdquo
ldquoThe technology is supplied by Rowa Tunneling Logistics and this is the first
time it is being used in Asia A jaw crusheris placed at a distance of about 40-45
meters behind the face The blasted muckextracted from the face is fed to the crusher
to reduce the lump size and then through
an overhead conveyor transport system
it is then transported out of the tunnelrdquoldquoThis enables free movement of man
and machinery in the lower area or spe-
cifically on the ground area If we were to

coarse aggregates as prescribed in IS383-1970
The plant was up and running in good
condition and performing to AFCONSrsquos
satisfactionldquoWe have worked with Metso in earlier
projects and are quite impressed by thekind of technology amp services they provide
We have a history together so the trust fac-tor also comes inrdquo explains Dhiman on their
choice of Metso as a partner
Service makes the difference
ldquoMetsorsquos services have made a big dif-ference in the project Without them we
would still be struggling with the machin-
ery and production The service is really
good and the service engineers are knowl-edgeable prompt and quick to act Any
problem can be solved by Metso We donrsquothave to wait until a service engineer turns
up ndash they have the capacity to solve prob-lems over the phone as wellrdquo says Dhiman
ldquoThe Metso plant didnrsquot create any prob-
lems for us We had problems in logistics
the feed was sticky and the weather condi-tions were bad but thankfully we did not
face any problems with production and
efficiency as the Metso plant is performing
very wellrdquo Dhiman concludes

When the going gets tough

Sensitive projects require the best technol-

technology provider not only because of
the long-standing business relationshipbut also for the sheer consistency in prod-

strives for
ldquoAfter signing the project we faced alot of road blocks including extreme cold
avalanches roadblocks less oxygen ndash you
name it we faced itrdquo explains Ankit Dhi-
man Plant Manager at AFCONS-Strabag The Rohtang valley is known for its
notorious avalanches and landslides SoAFCONS had to take extra steps and safety
precautions against hazards on the site
ldquoIn this freezing cold not just us humansbut also the machines are at increased risk
of damage I remember when we used
to run the plant during winter the diesel
engines would freeze We had to constantlyheat up the fuel container to get the plant
running And even the sand in the sand
trap would freeze so we had to clean it on
a daily basis to stop the pipes from mal-functioningrdquo Dhiman adds
Plant designed for difficult terrain
Difficult terrain coupled with space con-straints led Metso engineers to put their
minds together to come up with a suitable
plant configuration After studying the
requirements of the project Metso sug-
gested a 150-tons-per-hour three-stagemodular plant using a C106 jaw crusher
a GP11F secondary cone crusher and a
B7150 tertiary vertical shaft impact crusher
In addition considering the unpredict-ability of the feed the plant was about
to reach a point where the amount offines to be handled could be increased
dramatically Metso strongly suggested the TK11-27-3V grizzly scalper and this became
the first-ever TK scalper to be supplied by
Metso to an Indian customer Also in order
to get better products a sand trap SF2360was added to the configuration
The sand trap is important equipment

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo
In 2011 Metso commissioned about
10 new processing units in France like
the one at La Mariais quarry

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Smooth transition to new-generation jaw crusher in Germany
Roumlhrig is a German company with a rich heritage The company has been quarrying granite at its plant in Bergstrasse inthe Sonderbach district of Heppenheim for three generations
TEXT amp PHOTOS Ralf Goffin
Roumlhrigrsquos superior product variety is onereason why the companyrsquos proximity to its
customers can be understood in more than
just physical terms The companyrsquos high
level of innovation has allowed it to estab-lish itself as a reliable supplier of materials
both regionally and internationally This
operational and technical expertise always
manages to keep in step with growing
market requirements
In terms of technical processing equip-
ment Roumlhrig has used a Nordberg C160stationary jaw crusher from Metso since
1992 At the start of 2012 it was finally
exchanged for a more up-to-date version
from the same model range
Metsorsquos C Series is specifically designed
to pre-crush hard rock and can cope effort-
lessly with even the hardest of materials
The dimensions of the new stationary jawcrusher are identical to those of the old
one which means that it could simply be
slotted into the housing vacated by the
previous version

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

sideways off its mount An initial test run
with materials was carried out around oneweek later after all the electrical cables had
been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos
chipping plant Roumlhrig is convinced that
the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for

ldquoWith the same number of employees we
can achieve 30 more productivity with
our new LT550GPF unit The high-capacityFS screen has also eliminated the bottle-neck often seen at fine screeningrdquo says
Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

Third-generation Managing DirectorMarco Roumlhrig expects the new machinersquos
service life to be just as long as the previ-
ous model due to the product upgrades
that have been implemented The integral motor base is another plus
point in models made by other manu-
facturers it is located outside the crusher
This element of good fortune ensured that
Roumlhrig could reuse the housing withoutany additional rebuilding
Another advantage lies in the revision
of the guards for the C160rsquos drivetrain andflywheel The sturdier construction method
used for the crusher requires fewer parts
which facilitates easier installation andmaintenance and it makes it simpler to
access the motor
Under the watchful eye of Metsorsquos
Assembly Manager Maik Engelstaumltterthe entire project including removal and
installation was successfully completed
within two weeks
Installation making the most
of the available space
Roumlhrig will likely remember the day the
new crusher was installed for a long time
the pitman and main frame were deliveredseparately prior to installation and assem-
bled on site It took just one hour to replace
the old stationary crusher with the new
model A lorry-mounted crane was used toposition the 85-ton crusher with millimeter
precision in the crushing plant Once the
new crusher had been positioned in theexisting steel structure the next task wasto fix it into place as securely as possible
despite the limited space Special vibration
dampers were installed at a height of two
meters to prevent the crusher from sliding

been installed
Simultaneously with the installation
of the C160 which is the first of the latest
generation of crushers to be installed in
Germany a new Nordberg GP100 conecrusher was also being installed in Roumlhrigrsquos

the technical improvements made tothe new Metso crusher can only be an
advantage worldwide
Roumlhrig places great value on consistent
product quality maximum added valueand optimum refinement of its product
range Bearing in mind that Roumlhrig has
enough reserves of raw material to last
for the next 150 years the company canconfidently continue to develop with an
emphasis on quality rather than quantity

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing

The processing installation is of the horizontal type with a primary station located 56 meters below the site access road to keep it hidden from view
The crushing and screening installation at
Charierrsquos CM La Mariais quarry (at Donges
on the Loire estuary) has been in opera-tion since September 2011 Based on theoperatorrsquos ideas it was designed by Metso
to replace a worn-out installation installed
right on top of the seam being extracted
Since its commissioning it has becomethe second quarry in the company to
receive ISO 14 001 certification

tertiary material of sand and gravel for the
local market to use in concrete surfacingprefabrication etcrdquo
Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of
020
Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection
visits and carry out preventive mainte-nance and any necessary repairsrdquo

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle

unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Incorporation of a screening station
The stone extracted from La Mariais is
according to the quarry granitic gneiss
sound and homogeneous with a LosAngeles index of 15 good wear resist-
ance with an MDE of 10 a true density of
265 and a certain abrasiveness (2000 gt)ldquoCharacteristically it has a tendency to form
blocksrdquo Leblin points out
The main criteria in designing the instal-
lation was to provide an output of 600000metric tons from one station (38 hours
week) to produce materials aimed at the
concrete and surfacing markets ldquowhich
involved providing a tertiary station withscreening plantrdquo he adds
With this new unit the operating com-pany expands its product range through
the addition of fine materials obtained
from the tertiary screening station This unitis capable of producing 170 tonshour of

Preserving the environment
and optimizing safety
The screens have motorized bogies and
retractable walkways to facilitate access
when the screens are opened for main-tenance Other walkways provide access
to the tunnel input feeders The feederscan be isolated with hydraulic rod gate
bars this hydraulic assistance eliminatesthe need to use a heavy hammer to lodge
these metal bars
All conveyors transporting fines (02
and 04) are covered with a tarpaulin to
avoid flying dust and all the screens arehooded (metal cover with Trellex seal-
ing) The Brunone company has installed
dust-tight containment at the outlet of the
tertiary station crushers (HP300 and HP4)on the belt located under the screens
and under the hoppers located belowthe tertiary screens The crushers are put
under negative pressure and the finesare extracted through sleeve filters (7000
m3 h) with declogging which deposits the
dust back onto the conveyor belt
A high-pressure 100 bar water mist sys-tem has been installed at the primary sta-
tion discharge at the secondary crusherrsquos
discharge chutes (Omnicone) and at the
transfer points on the belt
Designed to last
ldquoThis type of new installation can easily last
thirty yearsrdquo affirms Project Leader Bruno
Peix of Metso ldquoIt quite simply depends on
how well it is maintained Thatrsquos why weprovide maintenance contracts that call for
our technicians to make regular inspection

Aarno Kostamo Managing Director of
Kone-Kostamo Oy one of Finlandrsquos biggest
crushing contractorsAccording to Kostamo the high capacity
of the GP550 gyratory cone crusher easily
handles feed from the C120 and C125 jaw
crushers For the contract with the Talvivaara
nickel mine the LT550GPF is being fed bythe brand new Lokotrack LT120 jaw plant
Average capacity 300 tons per hour
Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm
aggregates are also being produced
The rainy summer increased the need
for road gravel along the muddy roadswhich must endure dump trucks weighing
as much as 260 tons
ldquoThe mobile process consisting of the
LT120 jaw plant and LT550GPF cone plant
is cost-effective while aggregates of vari-ous sizes can be produced in a two-stage
operation and with high capacity The con-trolled stroke and elliptical movement of
the FS screen secure big passing throughcapacitiesrdquo Kostamo explains
Operated in two shifts for a total of 16
hours per day the LT550GPF has logged
more than 600 working hours over a two-month period

Longer perspective than
a single quarter needed
Kone-Kostamo Oy was founded as an
earth-moving company in Kemijaumlrvi
Northern Finland in 1956 The company
expanded its operations to include crush-
ing contracting in 1964 and later on
switched to concentrating fully on crush-ing activities
Kone-Kostamo consistently crushes
and screens around 28 million tons ofaggregates annually and has net sales of
between EUR 8ndash9 million
ldquoWe believe that issues within the crush-
ing industry including the purchasing ofmachinery must be studied with a longer
perspective than a single quarter The
secret to our success has always been our
solid work ethic and professional employ-eesrdquo Kostamo sums up

Talvivaara Europersquos largest nickel mine uti-
lizes large quantities of aggregates Kone-Kostamo has contracted several million
tons of different end products for the mineIn August 75000 tons of 0ndash63 mm
road gravel was crushed Smaller amountsof finer 0ndash6 mm 0ndash16 mm and 0ndash32 mm

Monitoring-based reporting is vital for
assessing the performance of a mobile
crushing plant Metso provides suchreporting tools through its plant-wideautomation system Metso DNA (Dynamic
Network of Applications) with its infor-
mation platform that links all the mobile
crushing and screen units together as oneentity Basically there is a lot of measured
real-time information available in every
crushing plant On-line information is
obtained either from each Metso crusherrsquosmachine automation system IC (Intelligent
Controller) or from separately installed
additional sensors and belt scales
All the collected data is sent to a motorhome using wireless communication
based on WLAN technology The motor
home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The

unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

home is a purpose-built environment
inside an on-site container In this environ-ment selected variables can be monitored
for assessing the plantrsquos performance And
to make all this even more flexible the
data can be transmitted to a crushing plant
company office using GPRS3G mobile
data communication technologies Thismakes all the last-minute reports acces-sible to the crushing plant managerial staff
at anytime and basically anywhere within
reach of the cell phone network
Production and fuel economics reports
Essentially monitoring and reporting can
be customized to fit the customerrsquos needs
However there are certain off-the-shelf
reports that provide a lot of useful informa-tion for plant supervision The production
report is one of these Requiring at least one
belt scale for measuring the total produc-tion the production report shows the pro-duction rate (tons per hour) for a selected
reporting period eg a day or a week The
production report constantly keeps track of
the plantrsquos production storing all the datathroughout the plantrsquos life cycle
Performance monitoring and reportingfor a mobile crushing plantTEXT Pasi Airikka PHOTOS Metso
unit during which the unit is running By
storing the availability times between start-ups and shutdowns the crushing plant
operation time (hours per dayshift) can be
recorded analyzed and reported In addi-
tion the availability report can be tailored
to evaluate efficient crushing hours during
which the plant is really working and pro-ducing aggregates Consequently the ratio
(0-100) between efficient crushing time
and total running time can be reported forany selected period of time This boosts
the efficiency of the plantrsquos operations
and results in better productivity
Reports on non-choke
or inadequate feeding
Non-choke feeding to crushers is avoid-
able through smart plant-wide crushingplant controls But estimating its severity in
a systematic manner is not straight-forwardwithout constant monitoring and reporting
The crusher choke feeding report makes
use of the crusher cavity level sensors byanalyzing their level measurements By
calculating average and min-max values
and deviations from the average it can be
shown how often the single crusher suffersfrom non-choke feeding to it
In some cases the bottleneck in the
crushing plantrsquos productivity is the material
feeding to the process In mobile plants thefeeding is human operated and therefore
subject to variations Occasionally the sizeof the human-operated machine simply
does not allow for adequate feeding to thecrushing plant There are specific reports
indicating time periods when the crushing
plant suffers from inadequate feeding
Condition monitoring for
crushers and screens
Machine-specific condition monitoring
focuses on vibrating components in
crushers and screens such as drive shaftbearings safety plate wearings and gears
The low middle and high frequencies ofmonitored components are measured and
supervised in real-time to detect abnor-malities due to slow or fast wear looseness
or imbalance

Condition monitoring provides a view tovibrating crusher and screen components forpredictive equipment maintenance
The daily production report shows the hour-by-hour production trend and distribution chartfor a selected day with min-max average andvariation statistics for comparison
Fuel consumption is always an interest-ing concern The fuel consumption reportgives the fuel consumption of each crush-
ing unit (liters per hour) and their total
consumption (liters per hour) for a selected
reporting period and can track fuel con-
sumption changes over timeCrushing plant availability can be
assessed as well The availability report
calculates time periods for each crushing
