# ball mills volume

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a5′ x 5′Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as5′ x 5′where the shell is 5′ inside diameter and the working diameter is only 4’8″ with the …

Generally, filling the mill by balls must notexceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L: D is, usually, accepted in the range 1.56–1.64.

The energy input to a mill increases with the ball charge, and reaches a maximum at a charge volume ofapproximately 50% (see attached figure5 Energy input versus charge volume), but for a number of reasons, 40-50% is rarely exceeded. The efficiency curve is in any case quite flat about the maximum.
