This isn t reported in a standard ball mill work index test but the method of Levin 1989 can be used to calculate a "Levin B value" which is the kW·h per revolution of a Bond laboratory ball mill. Dividing ball mill grindability (g of product/rev) by the Levin B (kWh/rev) gives the desired units of measurement (g/kWh).
