Metso Outotec says it is launching the mechanical skew control HPGR (High Pressure Grinding Roll) retrofit kit for improved throughput and energy efficiency on the heels of its new HRC™e HPGR release.
The HRC HPGR was launched back in 2014 pioneering the use of flanges and non-skewing design and, now, those same benefits can be had on existing, non-Metso Outotec machines, the company says.
The new HPGR retrofit kit takes the key components responsible for minimising skew from the HRC and makes the technology more accessible without the major investment or need to acquire a new machine, according to the company.
“We are very excited to introduce the new flanged roll with mechanical skew control HPGR retrofit kit, which allows customers to maximise the performance of their existing equipment without the capital expenditure investment of purchasing expansion machines,” Jack Meegan, Product Director, SVS, Stirred Mills and HPGR at Metso Outotec, says. “This is truly a value option for an extended customer reach.”
Key benefits of Metso Outotec HPGR retrofit kit include the ability to increase throughput by up to plus-20%; improved energy efficiency with the flanges ensuring even breakage rates across the whole width of the roll; reduced circulating loads as less material bypasses the rolls and more ore continues to the next stage of the process; and reduced wear costs with the flanges allowing harder studs for longer tire life.
