### Side effects of converting Ball Mill from Grate to

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 350t/h. After conversion it s a nightmare to obtain 90 passing 75mic at the same throughput. No change to the cyclones done. For overflow ball mills the charge should not exceed 45 of the mill volume .
