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.

Here are six categories of cement production that have potential for optimization. Raw Materials. The first step in the cement process is the recovery of the limestone and sometimes the extraction of clay. Online elemental analyzers can monitor material chemistry in real time, allowing for adjustments that will help extend the life of the quarry.
