PROCESS CONTROL FOR CEMENT GRINDING IN

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

The Cement Manufacturing Process Advancing Mining

2015-8-20  Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are
