Critical rotation speed for ball-milling - ScienceDirect
03/08/1999· To examine the dependence of critical rotation speed on ball-containing fraction, we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion, we chose this fraction range. A jar of ball-mill consists of a cylinder and two lids.
