High-Pressure Grinding Rolls (HPGR)

Leading the Laminated Crushing Revolution for Superior Efficiency.

Inter-Particle Crushing Excellence

The HSM HPGR utilizes extreme hydraulic pressure to crush material against itself within a compressed bed. This “laminated crushing” not only reduces particle size but also creates internal micro-cracks in the material. Whether you are producing high-grade manufactured sand or pre-grinding metallic ores, the HPGR delivers significant energy savings and superior grain shape compared to traditional impact or cone crushers.

Core Technology

  • Tungsten Carbide Studs: Extreme wear resistance.
  • Hydraulic Relief System: Instant protection from tramp iron.
  • 30% Power Reduction: Compared to VSI crushing.
  • Micro-Fracture Tech: Increases mill efficiency by up to 35%.

Technical Applications

Application Case Key Benefit Performance Gain
Pebble Sand Making Cubical shape, <8% needle content -30% Energy Consumption
Metallic Ore Pre-grinding Extensive ore micro-fractures +20%-35% Ball Mill Capacity
