High pressure grinding rolls (HPGR) are commonly used in various applications in the mining and minerals processing industry, including crushing of hard and abrasive ores such as gold, copper, iron ore, and diamonds. They are also used in cement manufacturing, industrial minerals processing, and pellet feed preparation in the iron ore industry.

HPGR application fields

High pressure grinding rolls

Mineral Processing: HPGRs are extensively used in the mineral processing industry for ore grinding and liberation. They are employed in both primary and secondary grinding circuits for crushing and grinding of ores such as gold, copper, iron ore, nickel, and diamonds. HPGR technology is known to produce finer particle sizes with reduced energy consumption compared to traditional grinding mills, making it a preferred option in mineral processing operations.

Cement Industry: HPGRs are utilized in the cement industry for grinding raw materials such as limestone, clinker, and slag. They are often integrated into the grinding circuit to increase throughput, improve energy efficiency, and enhance the quality of the final cement product. HPGR technology can help reduce specific energy consumption and improve cement grinding performance, leading to cost savings and environmental benefits.

Iron Ore Pellet Feed Preparation: HPGRs are used in the iron ore pellet feed preparation process to enhance the pelletization properties of iron ore fines. By subjecting the ore to high pressure and compressive forces, HPGRs help improve the particle size distribution, increase the surface area, and enhance the binding properties of the ore fines, resulting in improved pellet quality and productivity in the pelletizing plant.
