Based on these test results, a 6.7 m diameter × 2.1 m length SAG mill and a 3.3 m × 6.1 m ball mill were installed for commercial operation in closed circuit with a hydrocyclone. The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1
The mill is estimated to be capable of drawing the 5500 kW at the pinion at 75% of critical speed with a 12 to 15% or greater ball charge and a total charge of 28%. The mill should be able to operate at the design conditions (10% ball charge, 28% total charge) in the speed range of 50% to 75% of critical speed over the full wear life of the liners.
