High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. SGS comminution experts have developed a simple testing methodology to .
High Pressure Grinding Rolls – Crushing and grinding for ore and minerals processing Introduction High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. Since then, they have been successfully installed in a large number of plants throughout the world, mainly for cement and limestone. More recently, HPGRs have
The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
HIGH PRESSURE GRINDING ROLLS—A PROMISING AND COSTEFFECTIVE TECHNOLOGY OF ORE PRETREATMENT IN MINERAL PROCESSING M. KESSLER, Project Manager E. BURCHARDT, Chief Technologist Mineral mining and processing industry increasingly focuses on efficient grinding systems in recent years worldwide,
Aug 15, 2019· Depending on the requirements of the circuit, High Pressure Grinding Rolls have been found to consume as much as 35% less power than conventional SAG millbased circuits. This amounts to between and kWh per tonne and lower total cost of ownership.
HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .
High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing. ''s unique take on this technology, the HRC™ HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market.
The wear system in high pressure grinding can be classified as threebody abrasive wear, whereas the two rolls represent the body and counter body, the feedstock is the material in between which is free to move and slide in air or maybe water for weathered feed material as the ambient medium.

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
