Raw materials - Cement

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Raw material drying and grinding. The raw mix that is fed in to the mill has to be dried and ground to the required product specification (normally 16% retained on 90 microns). This is accomplished by grinding equipments known as mills. Mills belong to a class of equipments that accomplish comminution of materials in the fine range.
