BEST WAY CEMENT COMPANY

CHAKWAL


3/17

COMPANY PROFILE

In February 2004 owing to the growth in market demand,Bestway Group took the strategic decision of expanding its

operations through the setting up of a 1.8 million tonnes

per annum cement plant near Village Tatral of District

Chakwal, Punjab Province, Pakistan. This is the Groups

second Greenfield development project at a cost of US$

140 million.

In April 2005, the Prime Minister of Pakistan, Mr Shaukat

Aziz performed the groundbreaking ceremony for the

plant. Civil works for Bestway Chakwal were initiated inJanuary 2005, the Kiln was fired in May 2006 and the

plant went into production in June 2006 which is an

industry record.

WHAT IS CEMENT?

Cement is a material which is obtained

after the calcinations of argillaceous

limestone.

FUNCTION OF CEMENT

to bind the material

use for construction purpose

to form a compact mass


6/17

Manufacturing Method

There are two method which are used for manufacturing of cement

1. DRY Process

2. WET Process

Now only DRY Process is used for the production of cement due

to low energy consumption.


7/17

WET PROCESS

Raw materials are homogenized by crushing,

grinding and blending so that approximately

80% of the raw material pass a No.200 sieve.

The mix will be turned into form of slurry by

adding 30 - 40% of water.

It is then heated to about 2750F (1510C) inhorizontal revolving kilns (76-153m length

and 3.6-4.8m in diameter.


8/17

DRY PROCESS

Raw materials are homogenized by crushing,

grinding and blending so that approximately

80% of the raw material pass a No.200 sieve.

Mixture is fed into kiln & burned in a dry state

This process provides considerable savings in

fuel consumption and water usage but theprocess is dustier compared to wet process

that is more efficient than grinding.

MANUFACTURING OF

CEMENT The 4 primary constituents of the raw

materials used in the manufacture of

Cement are:

a) Lime

b) clay

c)laterite

d)bauxite

Raw MillAll the materials are ground in the Roller Mill


10/17

Pre heater & KILN

Ground material is cooked in

a rotating 66m long KILN

for 45 min

Cooked material is called

CLINKER

CLINKER is cooled andstored in CLINKER storage

SILO


11/17

Cement Formation

Clinker from SILO is mixed

with 5% GYPSUM

Both Gypsum & Clinker areground in Cement Roller Mill to

produce CEMENT

CEMENT is stored in

CEMENT SILO and is sent tothe packing plant

Kiln

A Rotary kiln is a pyroprocessing device used to raise materials to a

high temperature (calcinations) in a continuous process. Materials

produced using rotary kilns are Clinkers.

There are four zone of the kiln.

1) Calcinations zone

2) Transition zone

3) Burning zone4) Cooling zone
