  • PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL

    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 delay characteristics also dynamics changes within 2-4
