Bond Ball Mill Work Index Test Procedure

bond ball mill work index test procedure

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 710 grinding cycles which shows that the procedure is a lengthy and complex one and is therefore susceptible to
