  • 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.

    Gold Ore has found a way to harness this powerful energy and use it for something good. Chemical reactions are governed by the interaction of energy and matter. Imploding cavitating bubbles generate temperatures of up to 5,500176;C and pressures of around 1,000 atmospheres, creating a highly reactive environment for mass transfer and chemical reaction.
