Ball mills the grinding charge in a ball mill consist of cast or forged steel balls. these balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. the ball size is often in the diameter range of 20-75 mm. the biggest size is chosen when the mill is used as a primary grinding.Comparative batch tests on ball mill feed with the current and an alternative ball charge may show increased grinding rate through the size of interest, but lower rates at coarser particle sizes. locked cycle tests are then needed to determine whether a net increase in grinding efficiency will.
