  1. ball mill void volume calculation

ball mill void volume calculation

The sizing ofball millsandballmilling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teachmill...

For overflowball mills, the charge should not exceed 45% of themill volume. For grate dischargemills, the charge should occupy about 50% of themill volume. Bond developed a relationship that can be used to determine the percent charge byvolumeas a function of the vertical height above the charge, He, and the radius of themill, R, i.e.,
