The cement mill
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.
Process Training Ball Mill
Ball mills for cement grinding usually operate with a filling degree between 25 and 35 %.
