The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 – 15 kWh/ ton of raw mix whereas the VRM motor uses 7 – 8 kWh/ ton.

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.
