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 ...

Presently, in the actual production of the concentrator, the filling rate of the ball mill is 28–30%, and the processing capacity is 310–320 t/h. From Fig. 4, it can be seen that the processing capacity was 353.02 t/h when the filling rate was 32% based on the bond index test simulation calculation, which is 30–40 t/h higher than the

This means that mill capacity to produce the final product increased 17%. By increasing the amount of "by-pass" of mill product to mill feed (which simulates lower classification efficiency) from 0% to 37.5%, the relative work index increased up to 9% and the capacity of the circuit decreased 15%.

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...
