Pooling conditions are most commonly observed with low-aspect (diameter < length) mills or single stage mills with high recirculating loads, but intermittent pooling is also encountered in high-aspect SAG mills (Powell & Valery, 2006; Burger et al, 2011) with pooling exacerbated by a high fraction of (or total) pebble porting of the discharge ...

Examples are given of both AG/SAG and ball mills of how the model responds to changes in slurry level. These examples are used to explain the observed phenomena of slurry pooling and the decrease in power draw observed in ball mills after start - up when feed is first introduced into the mill. Keywords: SAG Milling, Comminution

In wet milling, the presence of a pool of slurry is generally the result of mill overfill. The effects of overfilling on milling kinetics have been examined. Assessment of milling efficiency has also been made. To this end, batch grinding tests were carried out at 75% of critical speed. A laboratory mill, filled with 20 mm balls, was used for ...
