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

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.

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.

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

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

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
