To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.

As a general rule, Ball Mill feed should not be coarser then 80% passing 1/4" on hard ores and 80% passing 1" on soft ores (cement clinker). To achieve a reasonable efficiency with the Ball Mill, it must be operated in a closed system, with oversize material continuously being re-circulated back into the mill to be reduced.
