3-D liner wear profile measurement and analysis in industrial SAG mills
Application of the proposed method in a 9.75 × 4.88 m SAG mill indicated that the liner wear profile along the liner length is non-uniform and the highest wear occurs between 1.25 m and 2.75 m of the mill length. The liners of the first half of the mill from the feed end showed more wear (19.1 g/t) compared to that of the second half (17.1 g/t).In the 1950s, Kennecott Utah Copper, an operating division of the Kennecott Copper Corp., purchased a nearby smelter and built a copper refinery, thus becoming a vertically-integrated copper producer with its own mining, milling, smelting and refining operations. semi-autogenous grinding (SAG) mill and two new 20 x 30-foot ball mills Innovations: The Secret to Staying Young copper
