Circuit high pressure grinding rolls (HPGR) in a cement - PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL …

The first commercial application of HPGR was in 1985 and its success resulted in increasing numbers of applications since then, particularly in the cement industry ( Kellerwessel, 1990 ). Tube mills having multichambers are traditionally used for cement grinding either in open or closed circuit operations.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
