Abstract. 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 third step in crushing, or tertiary reduction, depends upon what is required. Twoinch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½ or 5/8in. size before wet crushing, particularly in the case of ball milling.
