Optimum choice of the make-up ball sizes for maximum
1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles whereas smaller balls are more effective for the breakage of fine particles.

Comminution in ball mills and vertical mills differs fundamentally. In a ball mill size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured even though the particles are very much smaller than the bed thickness.
