Up to now, most of the scaling criteria identified for the ball mill process come from the investigation of the motion of granular media in rotating drum, without pebbles. Dimensional analysis has been extensively applied to describe the flow behavior of powders in rotating cylinders [15] , [16] , providing scaling criteria usually based on the

The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of extensive laboratory and pilot plant testwork. This showed the Cadia ores to be hard and competent necessitating the use of both a variable speed mill drive and pebble crushing.

The Pebble Crushing Circuit. Once a critical size has been established in a primary mill, an efficient means of extracting it, crushing it and returning the crushed product to the primary mill has to be designed.
