  • HPGR High Pressure Grinding Rolls

    HPGR or highpressure 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.

  • Particle Size Analysis for Mining and Minerals

    In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classifiion (separation by particle size) either for further grinding or the next step, concentration of the ore.
