Grinding Circuit an overview | ScienceDirect Topics
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 mm diameter cyclones.
