What's the Difference Between SAG Mill and Ball Mill

2019-11-26  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

Effect of ball and feed particle size distribution on the

2018-6-1  For the construction, one needs three size classes and these are the feed, the intermediate and fine size class. Depending on the objective function one might require an intermediate size class or a fine size class. In leaching or flotation, an intermediate size class is desirable while in a cement industry the fine size class is preferred.
