The discharge end of theGrate Discharge Ball Millhas at least ten times the discharge opening area, through thegrate slots, compared to the commontrunnion overflow type mill. Thedischarge gratesaredesignedto run clean and free of any blinding or choking. The pulp level in themillmay be varied by merely changing the pulp dilution.
[email protected]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.,
Get PriceWe 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.
