The software uses the particular power model bondbarratt, morrell mi, etc. to determine what is the transfer size where the ratio of e sag to e ball matches the ratio of mill power 11.5 in this example. this is the maximum efficiency transfer size where the mills will both operate at full power.

Top ball size 80 mm ore density 2.93 tm 3 table 5 presents results of a single ball mill survey. the survey measured motor input power. drives are assumed to have an efficiency of 0.96 and gearboxpinion efficiency of 0.970, so the model shell power draw is converted to motor input power by dividing by 0.9312.
