The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

In recent years, there has been a rapid advancement in the understanding of tumbling mills through computer simulation using the discrete element method (DEM). It has thus far been able to qualitatively capture the behavior of the charge in ball, semi-autogenous, planetary, and many other types of tumbling mills.

Optimum ball charge in a SAG mill is a function of many factors. Some are discussed below. For a SAB or SABC circuit. In general, the higher the ball charge the higher the throughput (and fine feed helps as well). Of course, you need a bigger ball mill. But, high ball loads mean higher ball consumption in the circuit.
