### 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.

In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill. The production of fine material (final product) increased with increased feed rate, and the relationship is a straight line in log–log space. This represents the well known first order grinding law which states that the rate of production of fines
