sprintcar: I'm not sure that the'mechanism' has ever been determined - I remember being at a gold mine where a 1200 hp SAG mill was installed- the oversize went to a small gyratory crusher, and often a steel ball from the SAG mill somehow made its way into the small crusher - when we went to do a liner change on it, the welders were asked to ...

The crushed pebbles fall directly onto the SAG mill feed belt and return to the SAG mill. SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a …

The Cadia Mine again ads process design with the first truly hybrid HPGRle -SAG circuit upgrading the circuit that had the world's first forty foot SAG Mill.

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.

design processing rates of the Cadia Hill SAG mill circuit and that could be easily manipulated were; SAG Mill Load Ball Charge - SAG mill power draw was guaranteed by the vendor at 13% ball charge and 30% total volume to be 20.96MW for the 40 foot diameter SAG mill. In practice this power draw was never achieved I-14 (Dunne et al 2001).

MW). It has been the industry standard for SAG mills above 13 MW capacity. However, pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia.
