The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.
The energy specific cumulative grinding rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge.
WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore) F80 = 80% passing size of the circuit feed, in microns. P80 = 80% passing size of the circuit product, in microns. Example. The dry feed of a ball mill circuit is 300 t/h. The power at the pinion of the ball mill is 1800 kW.
