Based upon a simplified grinding mechanism, an analysis of the selection function is made for vibration mills. The mechanism considered is that a particle nipped by two colliding balls is to be ground only if the ball impact generates or activates at least one crack within the particle and the crack is big enough for fragmentation. The derived selection function increases with increasing size ...
