  • Vertical ring magnetic separator for de-ironing of pulverized coal ash and method using the same
    Patent number: 8505735
    Abstract: A vertical ring magnetic separator for de-ironing of coal ash comprises a rotating ring (101), an inductive medium (102), an upper iron yoke (103), a lower iron yoke (104), a magnetic exciting coil (105), a feeding opening (106), a tailing bucket (107) and a water washing device (109). The feeding opening (106) is used for feeding the coal ash to be de-ironed, and the tailing bucket (107) is used for discharging the non-magnetic particles after de-ironing. The upper iron yoke (103) and the lower iron yoke (104) are respectively arranged at the inner and outer sides of the lower portion of the rotating ring (101). The water washing device (109) is arranged above the rotating ring (101). The inductive medium (102) is arranged in the rotating ring (101).
