Variables in Ball Mill Operation Paul O. Abbe®

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 ...
