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.
