    Foroverflow ball mills, thechargeshould not exceed 45% of themill volume. Forgrate discharge mills, thechargeshould occupy about 50% of themill volume. Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of themill, R, i.e.,

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

    We recently converted a grate discharge type ball mill (size5.7X8.6m) to an Overflow type. Before conversion, the ball level was 26%, and we were able to obtain a grind of90%+ 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.
