Metso HRC™ is leading the energy efficiency challenges in the comminution circuits, bringing in a step change with over 15% energy savings. When used with Metso Vertimills you can realize up to 36% savings.


High pressure grinding rolls are an energy efficient grinding solution, and now Metso has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.

Main features of the HRC™ HPGR are:

  • Patented anti-skewing Metso Arch-frame
  • Tungsten carbide studded tires with patent pending HRC™ HPGR flanges
  • Feed hopper with guide plates to direct the feed into the crushing zone
  • Hydraulic cylinders can be adjusted to provide the optimal crushing force
  • Variable speed drive train suitable to run between 110% to 30%* full speed (*select sizes run between 110% to 50% full speed)
  • Dust enclosure to provide a dust and noise barrier while also offering added protection for the main bearings


  • Increased circuit efficiency and capacity – flanges direct material to the crushing zone, maximizing the amount of ore crushed.  In a closed circuit pilot scale operation, this amounted to over a 20% increase in circuit capacity and over a 10% decrease in circuit specific energy
  • Improved availability – patented Arch-frame eliminates downtime associated with skewing
  • Increased reliability – anti-skewing Arch-frame prevents bearings from being damaged due to misalignment
  • Reduced operating costs – energy efficiency, longevity of  wear components including the studded tires and no use of grinding media all contribute to low operating costs
  • Flexible operating parameters – speed and pressure can be adjusted for changing ore conditions and downstream circuit demands
