Closed Circuit Grinding VS Open Circuit GrindingOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating CostsOpen 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 arrangement. Some conditions which do favor open circuit grinding such as small reduction ratios, reduction of particles to a coar…Basic Ball Mill Grinding Circuit .com
