When feeding the mill with harder material (right side of Table 1), the mill discharge becomes coarser. Consequently, solids recovery, circulating load and solids content will increase. With increasing solids content in the hydrocyclone feed the cut size is decreased by overflow throttling from 23 to 10 μm.

Its also possible to note in figure 7 that k from vertical mill decreased along the year, even reaching smaller values than those for ball mills in some points. This is due the wear of cyclones apexes and, consequently, the increase on vertical mill circulating load, which reached values over 500% by the end of the year.

The gravity modeling results showed the four QS48 machines would handle the full ball mill circulating load even at the expanded throughput of 3.1 Mtpa with gravity gold recoveries ranging from 64.8% for oxide ore to 80.1% for transition ore. The sulfide ore gravity gold recovery of 71.9% was used for design.

Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH .Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.

The increase of pressure difference indicates that the amount of raw materials entering the mill is greater than the amount of finished products, and the circulating load in the mill increases. At this time, the current of the feeding hoist becomes larger, and the slag discharge amount increases. And the material layer is continuously thickening.

Control of the circulating load is therefore important in the control of the particle size. A high circulating load at a fixed product size means lower energy consumption, but excessive circulating loads can result in the mill, the classifier or the pump overloading. Hence there is an upper limit to the mill feed rate.

Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =1.30)." By keep on increasing the circulating load, typically you reach a point where the mill is overfilled and milling efficiency decreases. thus, there is an optimum circulating load.
