Liners for the Grinders | E & MJ

E&MJ asked one of Australia's experts in SAG-mill liner technology, Dr. David Royston, about recent trends in SAG milling practice and how this has affected the design of liners. "In recent years, the trend to smaller top-size ore feed into SAG mills has been matched by a trend toward smaller but more balls in the SAG mill charge.

Kirkland Lake Gold - Detour Gold

The grinding circuit consists of two parallel lines, each having one twin pinion semi-autogenous (SAG) mill (36'X20') and one twin pinion ball mill (26'X40.5'). The gravity circuit currently recovers approximately 25% of the gold. The remaining gold in ore is sent to cyanidation followed by carbon in pulp (CIP) gold recovery.

What is an inching drive? - Motion Control Tips

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically ...
