Skewing is a vital feature for high pressure grinding rolls as feed variance, segregation and the presence of tramp materials are inevitable in real world grinding circuits and will lead to uneven grinding and selective wear of the tyres. Skewing allows maximum grinding pressure to be maintained across all particles, while potentially damaging ...
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.
