Quantifying Grinding Efficiency - Grinding
If the ball mills are in connection with hydrocyclones then the ball mills can't be evaluated by themselves but they need to be assessed as part of the grinding classification system. In any case the evaluation is simple: You need to take a sample of the feed to the grinding-classification system and a sample of the discharge of the system.

Milling - Our Equipment - British Rema
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').

Ball mill - Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
