What is HPGR? 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 ...

2020-3-17 · During recent years a worldwide trend towards comminution installations using High Pressure Grinding Rolls (HPGR) has been established [1]. This comminution practice was made famous in the 1980s by the research work of the German Professor Schönert. The technology has its foundations much deeper in the past [2].

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.
