  • Development of a Novel Grinding Process to Iron Ore

    2020-3-28 · Ore Blend Grinding at HPGR and Ball Mill. The ore blend was ground in a pilot-scale HPGR (1 m diameter × 0.32 m width) at a maximum feed rate of 50 t/h. The ground product was recirculated to the HPGR feeding hopper five or seven times, wherein every recirculation steps a sample was gathered for moisture and size distribution measurement.
