Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.

Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (eg pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.
