SAG Milling in Australia - Focus on the Future
The paper examines the current state of equipment and circuit design, with reference to Australian practice._x000D_
Following a review of the changes in milling applications over the last 15 years, developments in mill design are examined. Current issues include trunnion versus shell support; drive type and economic analysis for comparison of the various systems; the efficiency of the mill discharge system for slurry and pebble removal, and lining configuration. Peripheral problem areas such as pebble crushing and classification are briefly examined._x000D_
Circuit design issues are reviewed. The decision to modify the traditional primary crushed feed is examined with reference to recent and proposed installations. A retrospective look at fully autogenous installations and their successes is presented, and current views on increasing throughput are assessed._x000D_
Finally, future developments are anticipated in mill design and control, and competing processes are identified.
