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

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.
