Definition of closed-circuit grinding - mindatorg glossary
Definition of closed-circuit grinding A size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill ,
Grinding of cement clinker has been traditionally performed by the ball mills which can either be open circuit or closed circuit with an air classifier Selection of right mill for the specified duty is the most critical for circuit design, since it has the highest capital and operating costs
