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.

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feeds density to 80% of its solid volume, exceeding its compressive

High Pressure Grinding Rolls HPGRs compress and grind the particle bed in the operating gap between two counterrotating rolls. The floating roll is pressed towards the fixed roll to maintain a working gap and pressure set point. Increasing the operating pressure will increase the kWh/t.

High Pressure Grinding Rolls (HPGR) HPGRs are modern and efficient comminution machines, which are becoming more and more popular in mineral processing. In addition to the industryleading equipment that TAKRAF already offers to the mining industry, the TAKRAF HPGR is a benchmark in further developed comminution technology
High pressure grinding roll is fixed with two highstrength wearresistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space between the two rolls, suffered both extrusion and shear the crowd rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment.
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
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. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
#0183;#32;HighPressure Grinding Roll (HPGR) stands out as one of the most efficient types of grinding machinery, in terms of energy consumption and the size reduction rate. The prediction of the particle size distribution resulting from comminution in an HPGR device can be estimated using the Population Balance Model (PBM).
