Experimental set-up of laboratory AG/SAG mill with mill control PC, signal monitoring PC, and acoustic system. Mill charge consisting of 2 kg of ore sample, 860 ml water (∼70 wt% solid loading), and 5 kg of 23 steel balls [(size = ∼ 4 cm), fractional volumetric ball filling J b = 10.2 vol%] were used for the study ( Amelunxen et al., 2014 ).

Another control the grinding operator can often employ is the number of cyclones in the circuit. By increasing or decreasing the number of cyclones in the circuit the operator can influence the pressure drop across the cyclone. This will influence the size separation in the cyclone, the sharpness of the separation and, most probably the …

For example, if the application requires a high degree of control over the grinding process, a SAG mill may be more suitable due to its ability to handle larger volumes of ore and larger grinding media. On the other hand, if the process requires a finer product size and lower operating costs, an AG mill may be the better choice. Cost and ...

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.
