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.

Synthesis of Cu-CNT nanocomposite powder by ball
The main aim of this work is the fabrication of Cu-CNT nanocomposite powder using the MA by ball milling. The as-received dendritic copper powders change their shape sequentially to flaky, disk-typed particles and finally, to globular type particles. Also, the tendency of globular formation was prominent in the milled Cu-Cu coated MWNTs (multi ...
