The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

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.
