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. Product introduction YGM high pressure micro powder mill is referred to as micro powder mill or super fine grinding mill. The high pressure micro grinder is mainly used for the ultra-fine powder processing of more than 500 kinds of materials such as feldspar talc barite marble limestone carbon black and clay.

The difference of Raymond Mill and Hige pressure grinding

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 ... Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time.
