  • High pressure grinding rolls (HPGR) -

    High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals.

  • Pellet feed grinding by HPGR - ScienceDirect

    15-03-2015· Dry grinding may present an alternative in containing cost for very fine grinding by reducing the need for sedimentation, dewatering, pumping and filtration involved in wet grinding processes. The application of HPGR with dry classification by static V-classifier or a combined static and dynamic classifiers can generate a fine product as desired for subsequent beneficiation or pelletisation.

  • Ultrafine Grinding - an overview | ScienceDirect

    Ultra-fine grinding (P 80 ≤ 10 μm) has been proposed as an alternative to "unlock" gold from sulfidic refractory ores; however, the cost of size reduction to this level makes it applicable only for concentrates (Corrans and Angove, 1991; Gonzalez-Anaya et al., 2011), as is practiced at Kalgoorlie Consolidated Gold Mines, a joint venture between Barrick and Newmont.
