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.

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

The build-ups are caused by the centrifugal force acting to press the raw material particles against the walls of the vessels, and the material cohesiveness, which increases as the temperature rises. This tendency largely depends on the balance between the volatiles (chlorides, alkalis, sulfur) entering the kiln with kiln feed and fuel.

 — The model structure for the one-chamber or multi-chamber cement ball mills have been subject of various researchers. Benzer et al.
