Roller Mill Based on Experimental Method mdpi-res
There are usually four kinds of VRMs in the cement production line, including raw meal mill, coal mill, Clinker Mill and cement mill, and the vertical mill occupies a large energy consumption unit. Therefore, it is necessary to optimize the multi-objective parameters of the VRM in order to improve the grinding performance and reduce energyIn the past, high pressure grinding rolls (HPGR), vertical roller mills (VRM) had positive effects on the overall energy utilization of cement grinding however some quality issues had also been(PDF) Cements ground in the vertical roller mill
