2017-10-27 · 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 minutes. The fast dynamics necessitate closer attention to the process condition and taking corrective action in time. In this paper, the various conventional and modern control strategies to control the process variable available in VRM .
