    Performance enhancement tools for grinding mills SAIMM

    The load movement inside of a SAG mill can be monitored through the audible impacts of the falling stream of ore and grinding media with themselves and with the mill liners. The mill noise is a mixture of many different sound sources. The main source is the large number of small shocks between load components during tumbling of the mill load, audible as a continuous stochastic noise. An

    SAG Mill Control: It Shouldnt be that Hard womp-int

    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

    A thesis submitted for the degree of Master of Philosophy

    Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills are installed in the majority of comminution circuits in the mining industry. It is known that AG/SAG mill operation varies with the properties of ore that is fed into it and therefore, it is desirable to achieve optimal mill performance by understanding how the mill responds to operating parameters. However, the process of
