ball mill balls to powder ratio

Why the ball to powder ratio (BPR) is insufficient for . 15/6/2014 The ball to powder ratio (BPR) is a processing parameter that is frequently used in both mechanical (ball) milling and mechanical alloying A number of recent studies provided the BPR as a principal milling parameter while neglecting other parameters, such the vial volume, the diameter and quantity of milling balls and the
