The ball to powder ratio (BPR) dependent

2018-11-1  The intrinsic mechanism for the BPR's effect on the powder during ball milling can be summarized as follows: the BPR determines the collision frequency and the velocity of the milling ball. The larger the BPR is, the higher the stress frequency due to collison frequency and the stress intensity due to the velocity of milling ball.
