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 ...

between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions. The higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills (Mazzinghy et al., 2013).
