how to grind iron ore fines particle 2
How energy efficient is HPGR?
Fine-grinding and ultra-fine grinding of ore or concentrates in conventional ball mills results in energy consumptions that increase exponentially with product fineness. Wipf (2009) presented a flowsheet in which he proposed the installation of HPGR ahead of the Aerosion 'Disintegrator' for ultra-fine grinding of ores and/or concentrates.
