The original (base case) SAG mill liners comprised of 48 rows of shell liners and radial discharge type with 25 mm grate apertures. This liner system was suitable for the low competentfriable feed but did not perform well on the harder skarn and diorite ores, particularly when the power drawn was limited by increasing mill noise at
