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).
