Hard ore Work Index 16 = 100,000/65,000 = 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 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 ...
