Setting sustainable standards together: LOESCHE and Metso present groundbreaking dry grinding technology
Duesseldorf, Germany – Loesche GmbH announces the signing of an exclusive partnership with Metso Corporation. The aim of the collaboration is to introduce the pioneering Metso Loesche VRM dry grinding technology for a wide range of mineral processing applications.
The partnership combines Loesche's proven vertical roller mill (VRM) technology with Metso's comprehensive expertise in sustainable end-to-end solutions for mineral processing and global service capabilities. Together, the partners support the mining industry in achieving efficiency gains through innovative technologies and redesigned process flow sheets.
"With Metso at our side, we are excellently positioned to offer significant added value to the mining industry and actively shape the transition to more resource-efficient processes. Our VRM technology has a proven track record with more than 2,400 references in the cement and other industries worldwide. We are delighted to now be able to use this proven technology in mineral processing, where it offers considerable advantages," says Stefan Baaken, Managing Director of Loesche Australia and Global Head of Mining Applications at Loesche.
"We are very much looking forward to working with Loesche. The introduction of the Metso Loesche VRM sets new standards in sustainable crushing and brings significant benefits to the mining industry in terms of sustainability and efficiency. It significantly reduces energy consumption in one of the most energy-intensive steps and lowers operating costs through simplified flowsheets and reduced wear part consumption," says Bjorn Nielsen, Vice President, HPGR & Dry Grinding at Metso. “In addition, the Metso Loesche VRM provides a steeper, more uniform particle size distribution and reduced oxidation of sulfide mineral particles, which improves downstream processing performance and supports more sustainable, resource-efficient mineral processing.”
About Metso Loesche VRM dry grinding technology
The Metso Loesche VRM 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.
Metso Loesche VRM technology features advanced wear materials to meet the demands of mineral processing applications and ensure high operating availability. Advanced process control is integrated to ensure optimum operation, easy stop-start and rapid ramp up.
