Why the ball to powder ratio (BPR) is insufficient for

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 powder mass.

Why the ball to powder ratio (BPR) is insufficient for

2014-6-15 · Magnesium hydride powder (ABCR Germany, 98%) was milled in a Fritsh P7 premiumline planetary ball mill. The milling process was performed with different parameters, including the ball and powder mass, total milling time and number of cycles, but the ball to powder ratio (BPR) was kept constant in all cases. The resulting BPR was 6.2.
