摘要：
The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes convex in relation to particle size on a log-log chart, which has been observed experimentally. Further, the effects of ball properties and powder and ball fillings on the selection function or the mill capacity are examined theoretically and agree reasonably well with experiment.
