Modelling the Specific Grinding Energy and Ball-Mill ...
Bond work index: Wj= 26.0 kWhlshort ton From Eq. (6), the specific grinding energy is: W = 77.34 kWhlshort ton or W = 85.23 kWhlt For throughput 400 tIh production, the total required ball-mill power is: 85.23 kWhlt x 400 tIh = 34092 kW. If six (6) ball-mills are used, the power drawn from each mill is: (34092/6) = 5682 kW.
