HPGR technology is a qualified alternative for largescale comminution circuits and is becoming increasingly popular. The technology''s working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls.
Outotec is launching the mechanical skew control HPGR (High Pressure Grinding Roll) retrofit kit for improved throughput and energy efficiency on the heels of the new HRCe HPGR
At the same time, the specific energy consumption of the HPGR Pro is reduced by around 15 %. The uniform pressure profile in the milling gap results in better grinding and more even roller wear improving the service life of the rolls by up to 30 %. By reducing the socalled bathtub effect the rolls need to be replaced less frequently.
High Pressure Grinding Rolls are generally thought to only be effective in controlled dry grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGRs the flexibility to fit into a wide array of applications with both wet and dry classification.
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.
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. Read more SGS comminution experts have developed a simple testing methodology to avoid some of the difficulties associated with using HPGR.
High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer
With industry demand for high pressure grinding rolls (HPGR) on the up, Minerals is arguing that skewing is a vital feature for modern HPGRs to reduce wear, save downstream energy and ensure optimal grinding across the whole feed. The company was sharing its findings following the publication of a new white paper.
