The next generation of high-pressure grinding rolls has arrived, according to Metso Outotec, with the HRCe.
The HRCe HPGR follows the original unit, which was introduced in 2014 by what was then Metso. The HRC pioneered flange use and non-skewing design for the industry.
The “next evolution” now has the benefits of energy efficiency by up to 15%; lower circulating loads by up to 24%; and increased throughput by up to 19%.
Additionally, it has a lower installation capex versus its predecessor.
“Metso Outotec is the only OEM that has been able to design and develop reliable flanged HPGR technology that has demonstrated superior performance for many years in the mining industry,” grinding line head Christoph Hoetzel confirmed.
