2014615 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.

Effect of Ball Size and Ball to Powder Ratio Variation
20111228 Based on XRD results it was found that a ball to powder mass ratio of 20:1 required a shorter time for the formation of nano‐crystalline calcium carbonate. Moreover, it has been seen that the presence of randomness in choosing ball sizes leads to finer crystallite sizes.
