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.

Water injection helps to control the temperature in the mill. There are different causes of heat generation in the grinding process, so different water injection systems are required. For example, if the fresh material is very hot, water injection, e.g. clinker >120°C, a water injection system is used at the mill inlet.
