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.
DetailsIn the vertical roller mill which is widely used in the raw material grinding process, raw materials input grinding table are crushed and pulverized on it and transported to separator by kiln exit gas introduced into the mill as drying, transporting and separating purpose.
DetailsCoal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
