  • Developments in HPGR technology

    2015年3月12日  Screen apertures in the case of closed-circuit operations typically range from 5mm to 6mm in the case of wet screens, and typically 10mm for dry screens. HPGRs (high pressure grinding rolls) have been developed within the last decades for energy efficient processing of a wide variety of ores. Special interest has been raised by Quantification of HPGR energy efficiency effects on downstream
