Critical rotation speed for ball-milling

 · 1. Introduction Behavior of balls in ball-mills is very complicated, and has been attracted by many researchers who have studied to understand the phenomena of ball-millings. Recently, various phenomena in ball-mills, e.g., radial and axial particle size segregation , avalanche mixing 2, 3, and angle of repose of avalanche and shape of surface flow , have been found.

Analysis of Power Draw in Ball Mills by the Discrete …

 · First, simulation results on a wide range of ball mills are compared with available experimental data. Then the power draft predictions as a function of a few operating variables are shown. The unique feature of this method is that the mill power can be predicted for a mixture of ball sizes, different lifter geometry and lifter spacing, which is absent in other methods proposed in the …
