Features of High Pressure Grinding Rolls. Designing lifetime of high pressure grinding rolls, guarantee 8000 to 12000 hours, for some ores can be used over 20,000 hours; Applied the high pressure crushing mechanism, the machine will have the higher crushing efficiency, lager crushing ratio and wider adaptability.

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 ...

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces 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 [.]

The Global High Pressure Grinding Rolls (HPGR) Market analysis report published on is a detailed study of market size, share and dynamics covered in XX pages and is an illustrative sample demonstrating market trends.

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.
