In semi-autogenous grinding (SAG), the grinding mill inventory, (i.e. volume of total charge, volume of ball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest cost ($/t).

The mill's SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original 12 x 28-ft single-deck SAG mill discharge screen.

Mar 20, 2020· Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

AG and SAG mills can be designed for dry or wet grinding. The bearings are hydrostatic slide or slide shoe bearings. Usually, AG and SAG mills have a gear rim/pinion or direct drive. Our p rodu ct portfolio includes sizes from a laboratory scale to a diameter of 10 meters or more. For transport reasons, these mills consist of several flanged parts.

With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to 2.5) for a coarse mill feed (say F80 > 110 mm). If the mill feed size is fine, say 50 mm or 30 mm, then you are looking at a total charge to ball charge ratio of about 1.5-1.6.

The El Soldado SAG mill operates in open circuit where pebbles are rejected to a different grinding line (of crushers with single-stage ball milling).

A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure

In the rod, ball (wet and dry) and tower mills, the wear part has the highest share and maintenance ranks second, but in the roller mill and the SAG mill this is reversed. The lubrication item has the lowest share for all mills, as can be seen in Fig. 1. Download : Download full-size image; Fig. 1. Relative share of each operating cost item.
