  • SAG Mill Control: It Shouldn't be that Hard | E & MJ

    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, but not the weight of the mill itself. While many ...

  • BrainWave SAG mill - andritz

    BrainWave is ideally suited to stabilize the operation of SAG mills. Effective grinding in a SAG mill depends largely on how it is loaded. A mill containing too much material does not allow for adequate movement of the ore and balls. A mill that does not contain enough material does not take advantage of the autogenous grinding mechanism. In either case, grinding effectiveness is suboptimal ...
