Ø Effect of SAG Mill Feed Size Distribution and Ore

2021-1-12  Ø Recycle crusher availability was lower than that of the SAG mill. Ø SAG mill availability was lower than expected in the first year due to issues with the gearless drive and trommel panel failures. Figure 1 shows the ramp up of the Cadia Hill SAG mill by quarter. Throughput and availability are presented compared to the target or design basis.

Investigation of the effect of filling level on the wear

2021-5-9  While as the ore filling level increases to 30%, the collision frequency with energy of 2 × 10 −6 J is the largest, and the maximum collision frequency is about 5 × 10 4 Hz. For a static SAG mill, the increase in the ore filling level means that more particles will contact with the liner, but that may not apply for a rotating SAG mill.

An improved method for grinding mill filling measurement

2021-1-1  1. Introduction. Mill filling has a dominant effect on grinding mill performance (Apelt, Asprey and Thornhill, 2001), and therefore, its accurate measurement is vital for modelling grinding mill performance.Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAG mills; or balls and slurry for
