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.

For instance the rotational speed of the mill and hence the relationship between gravity and the centrifugal forces acting on the rock particles and the grinding media has a significant effect. The charge within a mill being run at 90% of its critical rotational speed will behave differently from that in one running at 75% in which gravity

mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al. 2000). For media sizing maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.
