Critical rotation speed for ballmilling
· To examine the dependence of critical rotation speed on ballcontaining fraction, we measured critical speeds at various ballcontaining fractions from to stepped by Since at lower fraction than we could not observe the centrifugal motion, we chose this fraction range. A jar of ballmill consists of a cylinder and two lids.

Critical speed
Critical speed depends upon the magnitude and loion of the shaft unbalance, the length of the shaft, its diameter, and the kind of bearing support. Many practical appliions suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed; however, there are cases that require speeds above the critical speed to work correctly.
