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.

The use of grinding aids in stirred mills has also been the subject of many investigations and consequently, it was stated that the use of GA in the stirred mills increased the grinding efficiency and reduced the specific energy consumption [15], [16]. Assaad et al. [17] examined the effects of amine and glycol based GAs on cement fineness.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
