Applying grinding curves to mill operation and optimisation

Applying grinding curves to mill operation and optimisation

The operation of AG/SAG mills is sensitive to mill filling, therefore developing grindcurves to relate mill filling to performance indicators such as throughput, power draw, and product size can assist in achieving optimal mill operations The throughput, power draw, and product size have been shown to peak at different mill filling levels
