The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%. For the 50 mm balls the respective increase in power and capacity is 28% and 42%.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The ball size distribution (BSD) in a mill is usually not known, as the measurement of the charge size distribution requires dumping the load and laboriously grading the balls into size classes. Fortunately we had one set of data as discussed below. The general non-availability of BSD necessitates the use of ball wear theory to estimate …
