Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite.
consumption and raw material calcination dropped 24%, from 610 lb C/ton of cement (0.31 tC/tonne) to 469 lb C/ton cement (0.23 tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement.

Composition and preparation. Clinker consists of various calcium silicates including alite and belite. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone.. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature .
