HRC™ 8

High Pressure Grinding Rolls (HPGR) are used for size reduction or rocks and ores. They work by compressing feed material between two rotating rollers, one of which is fixed while the other is floating. Metso’s high pressure grinding rolls are known as HRC™.  The HRC™ 8 is a simple design for maximum performance.

Metso’s HRC™ 8 Crushers are ideal for aggregates and mining. Suitable for both hard rock and softer industrial minerals. Whether you need to produce manufactured sand, turn waste material into sellable products, or work with materials that are notoriously difficult to feed, the HRC™ 8 is perfect for these applications.

Robust HRC™ high pressure grinding rolls

High Pressure Grinding Rolls (HPGR) serve to reduce the size of rocks and ores by compressing the feed material between two rollers. One roller remains fixed while the other rotates, exerting immense pressure on the material. This pressure facilitates the grinding process, resulting in the desired smaller grain size.

Metso’s HPGR, branded as HRC™, is renowned for its efficiency. Available in various sizes, these rolls cater to diverse application and process requirements.


HRC™ offers a significant boost in throughput, thanks to its flange design which optimises material crushing by drawing the feed into the crushing zone. This approach effectively prevents material from bypassing the rollers, enhancing efficiency and throughput.
In contrast, the patented arch-frame eliminates downtime resulting from skewing.
Moreover, users have the flexibility to adjust the speed and pressure of HRC™ based on material conditions and application needs.


HPGRs are widely recognised for their energy-efficient grinding capabilities, largely due to their capacity to manage a continuous material flow.
HRC™ equipment takes efficiency a step further by guiding the feed material directly to the crushing zone and dynamically adjusting speed and pressure to minimise energy wastage.


In contrast to traditional grinding mills, HPGRs operate without the need for grinding media. Moreover, HRC™ grinding rolls are renowned for their robustness and the durability of their wear components.
The anti-skewing arch frame design effectively safeguards bearings against damage caused by misalignment, thereby conserving both effort and resources.


Enhancing safety during maintenance primarily involves minimizing the frequency of required maintenance.
Through HRC™ HPGR, downtime has been notably diminished by integrating sturdy components, such as the studded tungsten carbide surface, which ensures optimal wear resistance for prolonged longevity.
The straightforward design facilitates effortless servicing, enabling quick and convenient replacement of critical parts.
