3. Factors affecting ball mills Cement fineness vs. grindability Every 100 cm²/g increase in cement fineness increases the mill power consumption by 12 kWh/t for a closed circuit mill 23 kWh/t for an open circuit mill, a sheer waste if this is not required by the market! 20 25 30 35 40 45 50 55 60 2500 3000 3500 4000 4500 5000
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.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential ...
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 15 kWh/ ton of raw mix whereas the VRM motor uses 7 8 kWh/ ton.
