  • Perfecting Hard-Rock High Pressure Grinding Performance

    There were and still are more hard-rock HPGRs in the pipeline as well as the completed installations indicating that the potential E MJ mentioned at the start of 2006—for HPGR technology to impact comminution as much as autogenous and semi-autogenous milling did—is being realized (E MJ January/February 2006 pp. 60-64). HRC™ HPGR Applications Common circuits When selecting an HRC™ HPGR model mining operators should consider ore top size capacity and overall circuit design. The HRC™ HPGR is best suited for crushing in high-tonnage hard rock applications.

  • High-Pressure Grinding Rolls HPGR Machine for Sale

    In the case of the HPGR much of the effort was placed in scale-up procedures. Several organisations did produce process models of HPGRs but they have been fragmented in their acceptance. Currently the most complete model approach is that reported by Daniel and Morrell (2004) who have developed an approach from the earlier model of Tondo (1997). There were and still are more hard-rock HPGRs in the pipeline as well as the completed installations indicating that the potential E MJ mentioned at the start of 2006—for HPGR technology to impact comminution as much as autogenous and semi-autogenous milling did—is being realized (E MJ January/February 2006 pp. 60-64).

  • 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. High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. SGS comminution experts have developed a simple testing methodology to avoid some of the difficulties associated with using HPGR.
