a scale up model for hpgr hard rock grinding

  • Application of population balance model to HPGR crushing

    The new modeling approach for HPGR crushing is based on population balance model. The breakage rate of the particles was defined as a function of specific grinding force and material characteristics. The model was developed for a wide range of data acquired from hard rock and cement grinding but only a few data was presented in the paper.

  • 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.

    High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in
