High-Efficiency HPGR Solution: Maximizing Yield in Hard Rock Processing

Advanced high-pressure grinding technology for energy-saving and high-capacity fine crushing.

1. Project Background

A leading mining enterprise faced significant challenges in processing high-hardness ores. Their traditional tertiary crushing system suffered from high energy consumption, frequent wear-part replacement, and a low yield of finished products. The objective was to implement a High Pressure Grinding Roll (HPGR) system to achieve finer particle size distribution while drastically reducing operational costs per ton.

2. The HSM Solution

To optimize the production line for maximum efficiency, HSM engineers integrated the HPGR technology into the core grinding circuit:

High-Pressure Extrusion: Using our High Pressure Grinding Rolls, materials are crushed via inter-particle compression, achieving an 85% finished product yield.

Wear-Resistant Technology: Equipped with centrifugal casting rollers, the system maintains stability even when the liner thickness is as low as 1 cm, ensuring a 90% utilization rate.

Impact Crusher

Intelligent Control: Features one-click hydraulic start and full-bin feeding to ensure the machine operates at peak pressure for uniform particle shape.
