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.

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 ...

Abstract— This study compares the energy consumption of high pressure grinding rolls with the laboratory rod milling tests and the pilot plant. Three types of minerals were used as test specimens namely: pyroxenite (I), pyroxenite (2) and pyroxenite (3). These test samples were ground using jaw and cone crushers to provide feed for
