In the early 1990scement grinding mill stand areas has progressedthere are many large mill production.The second phase is handled in a cement grinding millour vertical roller mill may be located in a different place to the clinker plant. Gypsum (calcium sulphates) and possibly additional cementitious (such as blastfurnace slagcoal fly ashnatural pozzolanasetc.) 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
