ATRITA pulverizers are manufactured by

Riley Power Inc. They are high-speed mills

that operate from 900 rpm for the larger

machines to 1800 rpm for the smallest

machines. They are designed to pulverize awide range of fuels such as bituminous,

sub-bituminous, lignite, coke, and some

industrial by-products.

There are two standard ATRITA pulverizer

arrangements. A single type consists of a

crusher, a pulverizer, an internally

adjustable classifier and a fan section. A

duplex mill combines two single ATRITA

mills to form a duplex machine. Thecapacity ratings for the duplex are double

those of a single ATRITA mill of the same

size. ATRITA capacity ranges from 7000

lb/hr for a 350 single mill to 70,000 lb/hr

for the 558 Duplex mill. Duplex ATRITA

pulverizers began with the 550 single and

larger mills. Smaller sized pulverizers were

not designed as duplex mills.

The majority of the existing ATRITApulverizers consist of three sections:

1) crusher section

2) grinding section

3) classifier and fan section

Each is mounted on the same

horizontal shaft.

Each section is designed for a specific task

during the pulverization process. All sizes

feature the same pulverizer component

sections that perform the same function,

just varying in size and throughput. TheATRITA mill is driven with a single motor

that is coupled to the shaft either with

a direct drive high torque motor or

through a clutch. For most units, this is

a centrifugal style clutch that allows for

a slower start up.

ATRITA mills provide the advantage of

having a complete pulverizer mounted on

one shaft all driven by a single motor.While the frequency of required

maintenance is greater than other

pulverizer designs, the overall out of service

time is less and doesnt require specialized

tooling or rigging. For some ATRITA sizes,

many of the wear parts are

interchangeable. Utility boilers were

often supplied with a spare mill to

maintain boiler output during a mill outage.

ATRITA mills have a relatively small

rotating mass that enables shorter start

up times. They can also be brought on line

and removed from service quickly because

of the no coal reservoir design. Overall,

the simple design and operational logic

make the ATRITA pulverizer easy to operate

and maintain.

Rotation ProgramsAlstom offers customers a systematic method

for rebuilding boiler related equipment and

returning this equipment to service. Alstoms

Regional Service Centers are the focus of this

program combining our extensive experience,inventory, rebuild portfolio and proven

processes to provide a unique service.

The R3 program is based on Rebuilding,

Restocking and Replacing components.

Rebuild

Complete disassembly and inspection of a

component. Worn out parts are replaced and

components repaired. The components are

rebuilt to strict procedures and tolerances.Upgrades to components can be included.

Restock

Once a rebuild is completed, the component

is placed in the customers exclusive stock

inventory at the Regional Service Center

nearest the plant.

Replace

Rebuilt components are returned to acustomer when needed to replace a similar

component requiring service. The replaced

component is sent back to the Service Center

for rebuilding and restocking.

Save up to 50% versus

purchasing new

Alstom can supply new Rotor Assemblies or

rebuild existing assemblies incorporating

upgrades to address operational or

performance issues.

Alstom understands the demands placed on

plant operators to keep their pulverizers

operating at peak performance. Coupled

with the reality of greater spans between

outages and shorter outages, efficient and

timely equipment maintenance programs

are vital.

Alstoms Rotor Rebuild Programs, tailoredto customer requirements, follow a proven

process that includes disassembly and a

thorough inspection of all components.

Worn out parts are replaced or repaired as

appropriate, and upgrades included when

specified. All repairs, reassembly and

dynamic balancing are performed to

strict tolerances and procedures.

The result is a piece of equipment returnedto as-new condition and backed by a

comprehensive warranty.

Additionally, Alstom stands ready to work

with owners of ATRITA Pulverizers to

design a rotor spares program that meets

their specific goals.

Robotic

DoubleWeldOverlayHammers

Alstom continues to design and develop

products for ATRITA mills that will meet the

changing needs of our customers. Ourperformance and availability upgrades can

help when looking at fuel switching and the

changing environmental regulations. Alstom

provides solutions to improve fineness,

provide longer wear life, reduce

maintenance costs, eliminate a number of

mechanical problems and improve the

overall reliability of your mill.

Robotic Double Weld

Overlay HammersThe Alstom weld overlay is a chromium

carbide base electrode applied to the

standard swing hammers that significantly

increases wear life. This corrosion and

erosion resistant overlay contains a

chromium carbide content greater

than 18%, resulting in 60-62 Rockwell C

hardness that makes it capable of handling

severe impact applications.

Advantages

Significantly more erosion resistant than

the standard hand-applied overlay Weld can be applied to standard

manganese hammers

(existing customer inventory)

Robotic application ensures

part uniformity

Benefits to User

Up to double the operational wear life

longer periods between hammer

replacements Less component wear downstream

Longer component service life throughout

the mill

Improved fineness resulting in less

unburned carbon

CT4 is a white iron alloy with a high

chromium content used in:

Wear plates

Crusher blocks

Breaker plates

Periphery liners

Fan blades

Fan bolt guards

CT4 is engineered to resist abrasion and

erosion in high wear areas of the mill.

Proprietary heat treating results in superior

hardness and toughness, and produces a

part that is less brittle, thus reducing the

risk of cracking during installation. In

addition, longer wear means better grinding

capacity and fineness for longer periods of

time resulting in an overall improvement in

mill operation and performance.

Advantages

Superior wear

Superior toughness

Less brittle resulting in less cracking

during installation

Benefits to User Extended operational life

Longer periods between

part replacements

Better coal fineness resulting in less
