Autogenous mills are also known as AG mills which is an acronym for autogenous grinding mills. It is socalled due to the selfgrinding of raw materials inside the grinding chamber: a rotating drum throws largesized raw materials in a cascading motion which causes impact breakage of larger particles and compressive grinding of finer particles.

generate highenergy ballrock impacts at the charge toe) can be estimated from the lifting rate and height of lift of material between the shell lifters. The energy required is a minor proportion of SAG mill power and this proportion falls as the liners wear (and lifting capacity falls) even when mill speed can be increased.

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 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

This type of ore should have been treated in a high ball charge SAG mill with variable speed capability. Example 2 An extremely competent granodiorite ore (low Axb and High BWi) was treated through a low aspect single stage SAG mill targeting a coarse grind (P80 150 m). Lower than target throughput and over grinding resulted.
