Circulating Load - an overview | ScienceDirect Topics

The result is that the circulating load could be much higher compared with a runoff system. In addition, the grid allows for a ball charge that is as big as we want it to be. In fact, balls are not at risk of exiting the mill. The flow that a grid mill is capable of is 10–20% greater than the flow in a runoff mill. Energy consumption is equal ...

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.

Choosing a SAG Mill to Achieve Design Performance

A further explanation is required to explain the importance of designing the SAG mill chamber to draw required power at optimum operating conditions of 75% critical speed and less than 30% by volume load. Recent studies in the three-foot diameter SAG mill are instructive. The following graph shows the relevant facts as Figure 2.
