Formula to calculate grinding media wear rate for cement mill
From this experiment we got following result: 0.002389 MWh/t. Now using standard formula we can calculate grinding media wear rate: Wear Rate (g/kWh) = 0.042 * H * D^0.67 * η. H=Hardness in Mohs Scale. D=Diameter of Ball (mm) η=Efficiency Factor (decimal) Factors affecting wear rate of grinding media.
