How Do SAG Mills Work: The main purpose of SAG mills is to handle the grinding aspect by either preparing it so the material can proceed to be further ground or come up with a finished product after going through this stage. If you think crushing and screening can be a good alternative for this mill you are wrong for sure.

(4% ball charge, 90% Nc) A cross between AG and SAG for competent, abrasive ores. As typically operated in RSA. 6 SAG mill (configurations 3, and 5 ) with recycle crusher

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...

throughput is being limited by a non-sag mill problem a coarse feeder can be selected during this time. This will result in the formation of a stockpile that is relatively fine. When the production problem is removed the sag mill feeders can be switched to those giving finer feeds, .

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 ...
