Sag Milling

It has been the industry standard for SAG mills above 13 MW capacity. However, pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia.

SAG Mill Control: It Shouldnt be that Hard

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

SAG vs Ball Mills – COMESA

Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't possess a single hardness. The existence of this variance is what causes fluctuations in SAG mills, moving from a high soft mineral treatment capacity to a low treatment capacity for harder minerals.
