Procedure for determination of ball Bond work index in the

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling. This happens after 7โ€“10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to
