The comminution circuit at vizcachitas, where the hpgr circuit will be incorporated, is a three-stage crushing circuit using a gyratory primary crusher, three cone crushers in open circuit and two hpgr as a tertiary stage arranged in a closed circuit followed by ball.
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 hrc™ hpgr is best suited for crushing in high-tonnage, hard rock applications. common circuits utilize high pressure grinding rolls in a number of ways: • tertiary crusher, followed by a ball mill or vertimill • quaternary crusher, followed by a ball mill or vertimill • in a pebble crushing circuit for a sag/ag mill suitable ore.
