Technical FAQ: HPGR Operations
Q1: What is the benefit of “Inter-particle Crushing” in HPGR?
Unlike impact crushers, HPGR compresses a bed of material between two rollers. This causes particles to crush against each other, leading to a much higher percentage of cubical products and creating micro-cracks that make the material easier to grind in downstream ball mills.
Q2: How does HSM protect the rollers from wear?
We use Tungsten Carbide reinforced roller skins. These studs form a protective layer of material on the roller surface during operation, significantly extending the service life and maintaining a high crushing ratio even with abrasive ores.
Q3: Why is a magnetic separator mandatory for HPGR?
Because HPGR operates under extreme hydraulic pressure, even small pieces of tramp iron can damage the roller studs. A high-strength magnetic separator ensures all metallic contaminants are removed before feeding, protecting your investment.
