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.
The cement manufacturing process is completed when the cooled clinker is ground once again in a rotating finishing mill. A combination of gypsum and limestone will usually be added in small amounts to the heated cement during this last grinding step, and coloring agents can also be added here. The fineness of the finished particles will vary according to individual preferences, and the cement.
