The mill was expected to produce a product of 80% passing 150 mm. The feed rate to the mill was 300 t/h. The ball mill grindability test at 65 mesh showed 12 kWh/t. The internal diameter of the ball mill was 5.03 m and the length-to-diameter ratio was 0.77. The steel balls occupied 18% of the mill. The total load occupied 45% of the mill volume.
For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. ... Bond …
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%.

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 ...
