Vertical Roller Mills for Coal Grinding | Industrial Efficiency .Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.coal grinding process,coal grinding process,Coal Drying and Grinding | Mill (Grinding) | Coke (Fuel) - ScribdFor the latest precalciner kiln systems, both ball mills and roller mills equipped with dynamic separators to improve the combustion process in the precalciners. 5.3 Ball Mills Compared With Vertical Roller Mills For grinding an average coal (HGI 55 and 10% > 90μ), the vertical mill consumes about 9 kWh/t for the mill motor.
