HPGR High Pressure Grinding Rolls

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

Enduron® HPGR Weir Group

Other HPGR equipment on the market use large lateral walls, or ‘cheek plates’, to reduce the materials exiting the high pressure area horizontally without being properly crushed. However, these cheek plates make it impossible for them to skew. By contrast, only our Enduron® HPGR feature a spring-loaded lateral wall that skews alongside the rollers, maintaining a distance of just 1mm to ...
