Installation Twin Pinion Sag Mill
Grinding Mills
SAG mill product feeds two parallel ball mills of m× m (internal diameter×length), each with a MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and % critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660
Girth Gears
such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries. By current standards, girth gears can be as large as 14 meters (46 feet) in diameter, meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in
