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 critical speed of a ball mill can affect the performance and product quality of the mill. If the speed is too slow, the grinding balls will not be lifted and will not effectively grind the material. On the other hand, if the speed is too fast, the grinding balls will be thrown against the outer wall of the mill, resulting in ineffective ...

It was found that the mean best fit value of n was 2.05, which is very close to what is expected from Rittinger's Law. The range of optimum n values, however, varied from 1.12 to 2.97, with a standard deviation around the mean of 0.50. It is expected that as particle size becomes finer, the value of the exponent n would increase towards 2, since …

Ball milling experiments were done in a high energy planetary ball mill at a rotating speed of 300 rpm. To avoid the occurrence of any undesirable polluted phases, the ball-milling experiments were halted periodically (every 1.8 ks) and then restarted when the temperature of the vial reached about 300 K.
