  • A Neural Network Model for SAG Mill Control

    SAG specific power range of about 3 to 9 kWh/t for this site. The design of the ore stockpiling and conveying system contributes to fluctuating size distribution with significant short-term segregation occurring under certain operating situations. Depending on ore type and feed size distribution each SAG mill will process between 700 and 3000 tph.

  • 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

  • Autogenous and Semi-Autogenous Mills FL

    SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software we closely monitor the mill impact location to boost
