  • Closed Circuit Grinding VS Open Circuit Grinding

    Open circuit grinding consists of one or more grinding mills, either parallel or in series, that discharges a final ground product without classification equipment and no return of coarse discharge back to the mill. Some very simplistic examples of open circuit grinding are see below and are made of a Rod mill, Ball Mill or a Rod mill, ball mill combination. Not all ores can be ground in an open circuit type of arra
