Ball mills can be designed to operate continuously (fed at one end of the system and discharged at the other), or on a batch basis for smaller, or intermittent volumes. They can also be operated either on a stand-alone basis ('open-circuit grinding') or in conjunction with a classifier which returns oversize product to the mill for further grinding ('closed-circuit grinding').
