Metso to Deliver High-Pressure Grinding Roll
07/31/2025 - A gold operation in Western Australia has ordered a portable crushing and grinding circuit from Metso based on their high-pressure grinding roll (HPGR), the first of its kind to be deployed in Australia.
“The objective is to increase stockpile volumes at improved quality that de-risks mill runtime and improves reclaim rates with a portable solution that integrates into the existing crushing and grinding circuit,” said Kai Rönnberg, vice president of minerals sales, Asia Pacific at Metso.
Metso said the machine has a portable NW800HRCTM HPGR with flanged and studded rolls, a portable NordwheelerTM NW200HPS cone crusher and interlinked Metso portable conveyors. The NW800HRC has low emissions and is energy- and resource-efficient.
“Implementing portable HPGR technology in the thriving gold processing industry is a major development, enabling miners to flexibly increase their capacity with a short delivery and commissioning time,” said Bjorn Nielsen, vice president of HPGR and dry grinding at Metso.
