What's the Difference Between SAG Mill and Ball Mill
2019/11/26The 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

Wet vs Dry Grinding
2012/1/30There has been a well established "truth" that wet grinding is more efficient than dry grind- ing. This should apply to ball mill grinding as well as autogenous grinding. It has been earlier shown that the effect of dry ball mill grinding increases considerably, when the fines are efficiently removed from the mill.
