How cement plant works?
1 Quarrying and blasting
The raw materials that are used to manufacture cement are blasted from the quarry.
The raw materials are loaded into a dumper.
3 Crushing and transportation
The raw materials, after crushing, are transported to the plant by conveyor. The plant stores the materials before they are homogenized.
4 Raw grinding
The raw materials are very finely ground in order to produce the raw mix.
5 Burning and cooling
The raw mix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2,000°C. The raw mix burns at 1,500°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.
6 Finish 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.
7 Storage, packing, dispatch The cement is stored in silos before being dispatched either in bulk or in bags to its final
