Definition of closed-circuit grindingA 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 …

closed-circuit grinder. [ ¦klōzd ¦sər·kət ′grīn·dər] (mining engineering)A grinder connected to a size classifier (cyclone or screen) to return oversized particles to the grinding operation in closed-circuit pulverizing.McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc.

Apr 15, 2004· A closed-circuit grinding system, usinga continuous vibration ball mill has been applied to the production of fine particles.However in most cases, the operational conditions are determined empirically. The reason for using empirical operational conditions is that …

Open circuit system means that materials pass through grinding machine one time. But ifunqualified materials should be reprocessed by classifying equipment and powder satisfied requirements can be final products, this case can be called closed circuit system. The advantages of open circuit system are simple process, easy operation and less infrastructure investment cost.
