Client: Codelco Chuquicamata - CHILE. Increased ability to Revesol Liner handlers. Overhauling the two booms to 3,000 kg capacity each, for SAG mill Ø 32'x 15'de long.Increase throughput and capacity in SAG millsSAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.SAG Mill Liner - Nanjing Manganese Manufacturing Co.;LtdBased on experience, mill liner designs have moved toward more open shell lifter volumetric capacity and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. Mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.Grinding Circuit - an overview | ScienceDirect TopicsThe SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity. (Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time.) The SAG mill was designed to treat 2,065 t h −1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of ...Paper # 25 - Copper Mountain Overview on the Grinding ...The grinding circuit for the Copper Mountain project consists of one FLSmidth SAG mill and two FLSmidth ball mills.
