During the grinding experiments, the effect of the grinding concentration to the stirring mill's specific productivity and grinding efficiency was explored under a 0.6 material ball ratio, a 110 rpm stirring velocity, a 90% filling rate of medium, as well as a 3:2:5 medium radio, where the grinding concentration was increased from 45% to 65% at ...
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%.

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...
