We recently converted a grate discharge type ball mill size 5.7X8.6m to an Overflow type. Before conversion, the ball level was 26, and we were able to obtain a grind of 90 passing 75mic at a throughput of 350th. After conversion its a nightmare to obtain 90 passing 75mic at the same throughput. No change to the cyclones done.
