How Ball Mill Ore Feed Size Affects Tonnage & Capacity
Soft ore Work Index 13 = 100,000/90,000 = 1.1 kwh/t 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.
