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 ...

Determination of the axial grinding media distribution in ...

The IsaMill™ with its internal classifier keeps the grinding media away from the discharge. This technology enabled the fine grinding of minerals in an open circuit. Since the classifier implies a current counteracting the drag forces due to the product flow, it gets more complex to understand the axial distribution of the grinding media. ...
