Interested to know how Metso Outotec has worked with customers to bring results?
HRC™ Series high pressure grinding rolls (HPGR) are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the are particularly productive in producing manufactured sand for asphalt and concrete production.
Mining operations. Industrial minerals processing. Manufactured sand production for asphalt and concrete production.
An intelligent flange design to maximize material intake. A patented arch-frame to eliminate downtime caused by skewing.
Reduced operating costs
No need for grinding media. Continuous material stream. Direct feed to the crushing zone.
Less required service. Design that allows changing critical parts simply and easily.

HPGR for mining operations
HPGR helps you to get more value from every ton of ore with the sheer production capacity and state-of-the-art features.
They can be used in a wide range of mining applications:
- Hard rock
- Industrial minerals
HPGR for aggregates production
The smaller HPGR models, HRC™ 8 and HRC™ 800, are specifically designed to meet the needs of aggregate and industrial minerals applications.
They can produce high-quality manufactured sand for asphalt and concrete production.
- High-quality cubical aggregate for all reduction ratios and fractions
- Consistent production
- Low noise and less dust generated
- Low energy and wear consumption
- Capability to process hard rock, soft rock, construction waste, and abrasive materials like limestone, river gravel, granite and basalt
Robust HRC™ high pressure grinding rolls (HPGR)
Building the world's largest HPGR
HRC™3000 is a new generation high-pressure grinding roll that eliminates issues found in traditional HPGRs, allowing the mining industry to reach a new level of energy efficiency.
The world's largest HPGR was installed at Freeport-McMoRan’s Morenci site in Arizona, USA.
