ACC Limited is one of the largest cement producers in India, established in 1963. The document discusses the cement manufacturing process at ACC. It involves blasting raw materials like limestone and clay from quarries, crushing and transporting them to the plant. The raw materials are finely ground to produce the raw mix, which is preheated and burned in a kiln at 1500°C to produce clinker. The clinker is then ground with gypsum and other additives to produce pure cement. Finally, the cement is stored in silos before being packed and dispatched.

4. CEMENT
Cement is finely ground hydraulic
binding medium for mortar and
concrete, consisting substantially
of compounds of CaO with SiO2,
Al2o3 and ferric oxide which have
been formed by sintering or
fusion. ‘Sintering’ means burning
at a temperature which cause
partial fusion of the material

6. THE CEMENT MANUFACTURING PROCESS
 BLASTING : The raw materials that are used to manufacture
cement (mainly limestone and clay) are blasted from the
quarry.

 CRUSHING AND TRANSPORTATION : The
raw materials, after crushing, are
transported to the plant by conveyor. The
plant stores the materials before they are
homogenized.

8. THE CEMENT MANUFACTURING PROCESS
 RAW GRINDING : The raw materials are very finely
ground in order to produce the raw mix.

 BURNING : The raw mix is preheated before it goes
into the kiln, which is heated by a flame that can be as
hot as 2000 °C. The raw mix burns at 1500 °C producing
clinker which, when it leaves the kiln, is rapidly cooled
with air fans. So, the raw mix is burnt to produce clinker
: the basic material needed to make cement.

10. THE CEMENT MANUFACTURING PROCESS
1.GRINDING : The clinker and the gypsum are very finely
ground giving a “pure cement”. Other secondary additives
and cementitious materials can also be added to make a
blended cement.

 STORAGE, PACKING, DISPATCH :The cement is stored in
silos before being dispatched either in bulk or in bags to its
final destination.
