The cement manufacturing process are
Blasting:
The raw materials that are used to manufacture cement (mainly limestone and clay) are blasted from the quarry.
Transport:
The raw materials are loaded into a dumper.
Crushing and Transportation:
The raw materials, after crushing, are transported to the plant by conveyor. The plant stores the materials before they are homogenized.
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.
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.
