Question: Dry samples of quartz, galena and limestone ores were ground separately in a standard laboratory size ball mill 305×305 mm with a total ball load of 20.1 kg. After 100 revolutions 93 they were screened through a 150 micron sieve. The amount retained was returned to the mill together with equal amount of fresh ore.

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 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to …
