Modification of SAG mill liner shape based on 3-D liner …

For any new liner design the charge behavior was studied to evaluate the location of the ball impacts. Application of the proposed method in a 9.75 × 4.88 m SAG mill indicated that the liner wear profile along the liner length was non-uniform and the highest wear occurred between 1.25 m and 2.75 m of the mill length.

The selection and design of mill liners

• Los Pelambres: "SAG mill liner progression from 72 rows with 8 degree face angle to 36 rows with less aggressive 30 degree face angle. Changes allowed for the mills to be operated safely at higher steel loads without increased risk of liner damage. Increased power draw resulted in increased primary mill throughput."

Mill Liners | Multotec

A broken liner, which is particularly severe for large AG/SAG mills, can arise from media impacting directly on the mill liner.
