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.
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.
All changes to the grinding circuit process must be made gradually and the effects of the changes studied before further changes are made. Normal Shutdown Sequence of Ball Mill and Grinding Circuit .
