Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced
Ball milling is one of the few unit operation that improves with increasing mill diameter If acceptable results can be obtained with a 12” jar mil then good result will certainly be obtained with a 72” diameter mill Of course there is the possibility of over milling obtaining a different particle size distribution or a need to change
