Control of the grinding media volume based on wear rates within the SAG mill, increasing the grinding media load in the SAG mill, the use of a blend of ball mill balls to increase finer size particles and smaller cyclone apex. These recommendations did not result in improvement in mill.
SAG and ball mills with grate discharge are not prone to locked charge events because of the high amount of rocks and balls compared to fine ore. The pulp dischargers of a SAG mill continually pump the finer material out of the mill, lowering the total amount of residual fine ore and thus improving the situation in respect to locked charge starts.
