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 ...

The energy requirements are defined by the SAG mill consumption, which in turn depends on the feed. This feed depends on the in situ ore grindability and the specific extraction sequence and any potential homogenization that may occur by using stockpiles. Two key inputs are required to infer the energy balance in time:
