1.. IntroductionSchönert (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 …

With KAMAT high-pressure pump systems, slabs and billets in rolling mills can be efficiently descaled hydromechanically. With the annealing of steel, oxygen reacts with iron on the hot metal surface. Iron oxides, so-called scale, arise. This has to be removed, for example in case of steel slabs or billets, through descaling.

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 feed's density to 80% of its solid volume, exceeding its ...

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.
