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 ...

This states that AG mills are designed at 18% ball safety, mills operating at maximum 12% balls get 6% ball safety, while operations at maximum 18% get 3% ball safety. The original statement was that all mills should be designed at 3% ball safety over their maximum operating load.

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed. Result #2: This mill's ...
