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.
How do you improve the industry standard for HPGRs? By taking proven grinding technology and a customer-focused evolution to enable superior grinding and energy efficiency.
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
Diamond
Iron-ore
Gold
Copper
Platinum
Molybdenum
Industrial minerals
Others
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.
Benefits
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
