The optimal performance of AGSAG mills is the key to successful plant operation. All AGSAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling which decrease throughput and increase energy consumption.
An updated data set for sag mill power model calibration This paper expands the SAG mill survey database published by the Author at Procemin 2013. The new database includes 49 published SAGAG mill surveys and includes mills from all over the world.
Energy efficient comminution circuits Mining processes require heavy capital investments and generates high operational costs which are mainly due to high energy consumptions. Of all the mining processes grinding circuits are the most energy intensive component consuming up to 10 times more than crushing and 100 times more than blasting.

ABSTRACT Simulation work was carried out to analyse how feeding a finer sie distribution to a single stage SAG mill in closed circuit with hydro cyclones at Freda Rebecca Gold Mine would affect throughput and specific energy consumption using an Excel based milling process simulator developed by
Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding both raw and cement.
The ore from a SAG or AG milling perspective. Conducted in a benchscale SAG mill the SPI174 test measures the energy needed to perform a standard sie reduction expressed as an index. All four breakage mechanisms found in the industrial SAG mill are represented in the SPI174 test which is the key to its scale
