A big gold operation in Western Australia has awarded Metso an order for what the OEM says is an revolutionary moveable crushing and grinding circuit primarily based on Metso’s Excessive Strain Grinding Roll (HPGR) know-how.
The plug-and-play resolution is a primary of its type to be deployed in Australia, it claims.
Kai Rönnberg, Vice President, Minerals Gross sales, Asia Pacific at Metso, mentioned: “The target is to extend stockpile volumes at improved high quality that de-risks mill runtime and improves reclaim charges with a transportable resolution that integrates into the present crushing and grinding circuit. The Metso resolution is fed by diverting a partial stream from the oversize of the present HPGR closing display screen, crushing it finer and stockpiling the ultimate product.
“Advantages embrace decreasing the circulating load, eradicating a number of materials re-handling steps and rising manufacturing charges throughout operation. This energy-efficient moveable circuit is cost-efficient to put in and shall be operational in 12 months.”
The tailor-made moveable crushing and grinding circuit for the gold processing plant consists of a transportable NW800HRC™ HPGR with flanged and studded rolls, a transportable Nordwheeler™ NW200HPS cone crusher with a skid-mounted Metso display screen for environment friendly classification and interlinked Metso moveable conveyors for seamless materials move. The moveable NW800HRC HPGR is a part of the Metso Plus providing due to its energy- and resource-efficiency and decrease emissions.
Bjorn Nielsen, Vice President, HPGR & Dry Grinding at Metso, mentioned: “Metso is the one OEM with an put in base of moveable HPGRs, such because the HRC 800, which is purpose-built for difficult combination feed supplies and hard-rock mining. As well as, the flanged roll HPGR know-how pioneered by Metso optimises vitality consumption and minimises circulating load on account of its superior grinding motion. This allowed us to supply a right-sized resolution that meets the client’s technical wants. Implementing moveable HPGR know-how within the thriving gold processing trade is a serious growth, enabling miners to flexibly enhance their capability with a brief supply and commissioning time.”
