Cement Manufacturing Process

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.
