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.
The speed of ball mill rotation is a critical parameter which determines the grinding efficiency and the end product quality. The optimum speed will differ depending on the mill's diameter, the size and density …
