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 raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single ...
