Mining Intelligence and News

Each SAG mill operates with two ball mills. The pebble crushing circuit includes three cone crushers working in parallel and one HPGR unit working in tandem with the cone crushers. An augmented crusher is fed directly with coarse ore stockpile material by a single apron feeder and the product is dry screened.Get price
