E ects of Ball Size on the Grinding Behavior of Talc Using
e ciency of ball milling is greatly a ected by the jar rotation speed ball size and ratio of balls and sample talc 22 24 25 . A faster rotation speed generally produces talc with a smaller particle size and lower crystallinity 11 . Recently developed high-energy ball mills reach rotation speeds of up to 2000 rpm and provide an opportunity

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