The SAG mills pulverize the ore into smaller particles. As the dual, 6000 horsepower motors rotate the drum, a series of lifting plates built into the walls of the drum repeatedly lift weighted balls and chunks of ore along the sides of the drum and drop them back onto the ore at the bottom of the drum.
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 ...
