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.

How HPGRs compare to conventional milling

Aug 19, 2019· 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.
