focused on this energyefficient grinding technology by utilizing a singleparticle roll mill as well as a 200 mm by 100 mm high pressure grinding rolls at the University of California, Berkeley, USA. They studied the effect of HPGR operating parameters and developed fundamental models to simulate high pressure breakage phenomena.
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.
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.

clay or claylike material that typically is high in magnesia and has specialized decolorizing and purifying properties. Fuller''s earth, which is very similar to bentonite, is used mainly as absorbents of pet waste, oil, and grease. Common clay is defined as a plastic clay or claylike material with a vitrification point below 1100°C (2000°F).
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. .

The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to hightonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energyefficient than grinding mills, not
High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
