Coal mill. The coal mill uses coal, coke or grinded pet coke with different size of balls. Larger sized balls are used for impact grinding and the smaller balls are used for attrition grinding. Cement mill. This is the final step in a cement manufacturing process. In this step, the clinker is ground together with additives in a cement mill.
