High Pressure Grinding Roll for advanced crushing |

Pebble Crushing. Our HPGR is great at de-bottlenecking your problematic pebble circuit. You know how easy it is for hard pebbles to get caught in circulation, small enough to escape the mills but too large to make it through your screening process. Our solution is to crush the pebbles with a cone crusher and then feed them to an HPGR.
