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.
1. Introduction. Schönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success resulted ...
2. Compared with other similar mills, the micro powder grinding mill increases the crushing pressure of the material by 800-1200kg under the action of high-pressure spring. 3. The feeding size is large, and the one-time average particle size can reach 6.5μm. Technical Data
High Pressure Grinding Mill Grinding. JOYAL High Pressure Mill is an improved type of Raymond mill. The purpose of the this kind mill is to grind non-flammable and non-explosive materials in the fields of building materials, mining, metallurgies and chemical industry with hardness less than 9.3 in Moh's scale and humidity less than 6 percent.
Pressure Grinding Rolls Versus Sag Mills. High-pressure grinding on a whole new level. Aug 31, 2016· FCX chose an HPGR over a SAG mill for its expansion because the technology, which crushes ore between two cylinders – or rolls – is about 30 to 50 per cent more efficient than SAG mills.

High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the Moh's hardness scale, metals and metal alloys. High Pressure Roller Mills are used in continuous operation or in a closed circuit with screening machines or classifiers.
HPGR or high-pressure 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. .
