“We are truly excited about the collaboration with Loesche. The launch of the Metso Loesche VRM dry grinding technology sets a new benchmark in sustainable comminution, delivering clear sustainability and efficiency gains to the mining industry. It significantly reduces energy consumption in one of the industry’s most power-intensive steps and lowers operating costs through simplified flowsheets and reduced wear part consumption,” said Bjorn Nielsen, Vice President, HPGR & Dry Grinding at Metso. “It also produces a steeper, more consistent product particle size distribution and less oxidation of sulfide mineral particles, improving downstream beneficiation performance and supporting more sustainable, resource-efficient mineral processing.”

“Together with Metso, we are uniquely positioned to deliver significant value to the mining industry and support the shift towards more resource-efficient operations. VRM technology already has a proven track record with more than 2400 references in cement and other industry applications worldwide, and we are excited to see it taken into use also in minerals processing, where it can provide substantial benefits,” said Stefan Baaken, Managing Director Loesche Australia, Global Head of Mining Applications at Loesche.
About Metso Loesche VRM dry grinding technology
The Metso Loesche VRM dry grinding technology is part of the Metso Plus offering. It can replace high-pressure grinding rolls (HPGR), horizontal mills in primary and secondary applications and tertiary stirred mill applications, while at the same time simplifying the process and bringing savings in energy consumption and operating costs. Downstream processes benefit from improved mineral liberation and steeper particle size distribution. Furthermore, advanced flow sheets incorporating coarse particle flotation, magnetic separation or other coarse beneficiation technologies can be facilitated, further reducing or even eliminating water consumption if fully dry processes are feasible.
