Metso Outotec is launching the mechanical skew control HPGR (High Pressure Grinding Roll) retrofit kit for improved throughput and energy efficiency on the heels of the new HRCe HPGR release. The industry standard was set when the HRC HPGR was launched back in 2014, pioneering the use of flanges and non-skewing design. Now, those same industry-leading benefits can be had on existing, non-Metso Outotec machines.

The new HPGR retrofit kit takes the key components responsible for minimizing skew from HRC and makes the technology more accessible without a major investment or need to acquire a new machine.

“We are very excited to introduce the new flanged roll with mechanical skew control HPGR retrofit kit, which allows customers to maximize the performance of their existing equipment without the capex investment of purchasing expansion machines. This is truly a value option for an extended customer reach,” Jack Meegan, product director of SVS, stirred mills and HPGR at Metso Outotec, said in a release.

Key benefits of the Metso Outotec HPGR retrofit kit include:

  • Increased throughputs, increased by over 20%;
  • Improved energy efficiency, as flanges ensure even breakage rates across the whole width of the roll;
  • Reduced circulating loads, with less material bypassing the rolls and more ore continuing to the next stage of the process; and
  • Reduced wear costs, as flanges allow harder studs for a longer tire life.
