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 …
Hardgrove testing machines use compression breakage modes similar to those in a vertical spindle mill, whereas planetary ball mills use high impact breakage modes . The HGI test was developed for coal fired power plants, and the target 75 μm size is based on what is required for combustion in pulverised fuel coal burners .
Grinding of coal to this level of fineness is referred to as coal pulverisation. The Vertical Spindle Mill (VSM) is one of the most popularly used grinding devices for pulverised fuel (PF) generation in coal-fired power stations worldwide. According to published figures, coal pulverisation is an energy intensive process.
