Semi Autogenous Grinding Mill - an overview

Ball mills have traditionally been used for fine grinding of minerals, and in these cases smaller ball sizes than in conventional grinding are used to increase contact area and decrease collision intensity [15], and lower mill speeds are used to cause the media to cascade rather than cataract, shifting the typical forces experienced from impact and towards attrition [16].
