Traditionally, the generated pebbles are re-crushed via cone crushers, however the hard and abrasive nature of these pebbles result into significant liner wear and frequent cone crusher downtime. Integrating a HPGR into the pebble re-grinding circuit can alleviate the wear component and provide an improved overall feed to the (S)AG mill.

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 […]
