Nov 26, 2019 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 mills ...
Continuous Ball Mill Circuit For Grinding. When the amount of ore in the mills was the same, no appreciable difference between batch and continuous opencircuit ballmill grinding was found this should be so, because the progression in particle size for the duration of a batch run would be expected to be the same as the progression from the feed to the discharge ends in a continuous
