High Pressure Grinding Roll (HPGR)

The Core Solution for “More Crushing, Less Grinding” in Modern Mining

Revolutionizing Beneficiation Efficiency

The HSM High Pressure Grinding Roll (HPGR) represents the pinnacle of energy-efficient comminution technology. By applying extreme inter-particle pressure, it micro-fractures the ore, significantly reducing the bond work index for subsequent grinding processes.

This “pre-treatment” allows ball mills to operate at significantly higher capacities while drastically reducing power and steel media consumption. For modern beneficiation plants, the HSM HPGR is the ultimate tool to slash OPEX and enhance profitability.

Why HSM HPGR?

Energy Savings: Up to 30% reduction in circuit power.

Increased Throughput: Boosts mill capacity by 20-50%.

Edge Protection: Advanced patented side-seal technology.

Smart Control: Fully automated hydraulic pressure regulation.

Inter-Particle Crushing Principle

Unlike conventional crushers, the HPGR works by compressing a bed of material between two counter-rotating rolls. The high pressure (up to 350 MPa) causes extensive micro-cracks within the particles, ensuring a finer product and reducing the energy required for the next grinding stage.

High Pressure Bed

Consistent crushing force across the entire roll width.

Automatic Control

Real-time hydraulic adjustment for varying ore hardness.

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.
