Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for …

The circuit consists of a single-stage, low aspect ratio (diameter:length = 0.5) mill, typical of the majority of SAG mills in the South African gold mining industry. These are locally known as run-of-mine, RoM, mills. The mill is operated at 90% of critical speed and with a volumetric load of 40%.

This paper discusses the evolution of SAG shell liner design and its progression to the Skip Row design. Case studies have been provided for the Skip Row design in a variety of applications such as Single Stage SAG (SSS), SAG and Ball (SAB), SAG and Ball with Crushing (SABC) and Pre-Crush at a variety of mill diameters …

Compared to 4" media, a larger 5" ball will: Coarsen the mill discharge size. Increase potential for liner damage/higher wear rate. Provide a lower number of impact breakage events due to the lower number of balls. Provide higher energy impact breakage events. In a way, the media size should be selected based on feed size and grate opening.

Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...

Once it is realized that about 75 to 80 of SAG energy is consumed in abrasion grinding and that less than 25% is consumed in impact breakage it is concluded that large steel may be overused in many plants. In addition, this situation exists in many plants because the SAG mill is too small and the ball mills too big for high efficiency.
