Grinding Mill Gr Ton Material Charge

power per ton of ore processed based on size reduction desired. Thus: W = 10 W • (—-— - —3—) 9 (1.2) 17 where W = power (kWh/short ton) P = 80% passing size of product (microns) F = 80% passing size of feed (microns). The power per ton W, is then multiplied by the throughput rate to yield the total grinding floor power
