Generally, the total load should not exceed five-quarters of the total capacity of the tumbling ball mill. Therefore, grinding steel balls generally account for 45%-55% of the total volume. In this range, the tumbling ball mill has the strongest working capacity. In addition, the shape and quality of the grinding media will also affect the ...

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 ...
