End and shell liner design in these mills is much the same as for SAG mills. The effect of liner design on performance is equally as important. For instance, in an iron ore operation using 6.4 m (21 ft.) mills, mill throughput was increased by 15 percent and power consumption reduced by 13 … See more

Semi-autogenous grinding mills (S AG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter.

The shell liner type, rotation speed, and ball filling percent are the key factors influencing the charge behavior inside the SAG mills, and consequently, their performance.

This study presented a newly developed wear detection sensor for monitoring SAG mill shell liner wear during operation. The developed wear sensor probe was embedded into the shell liner via a casting insert. Two sensors were installed in a 34FT SAG mill in the feed end and discharge end liners. Results indicated that non-linear …

Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.
