A SAG mill of diameter 9.0 m and width 6.0 m was charged to 40% of the mill volume with ore of SG 3.2 when the porosity was 38%. With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to the change in mill conditions. The mill was run continuously at 70% of the critical speed.

The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill. The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm.
