Abstract: SCTφ4.5 m magnetic dewatering tank adopts multi-level ring type magnet system to produce a more rational magnetic field, better facilitating the magnetic agglomeration of magnetic minerals so as to improve the recovery of magnetic minerals. The number of the magnet ring levels of the system can be adjusted to satisfy the need of upsizing design. The industrial test result in Dagushan Concentrator in Mining Co. AnSteel Group indicates that the dry ore throughput of this machine is 2.33 times that of the currently used φ3 m conventional one. At a similar feed, the performances of SCTφ4.5 m magnetic dewatering tank such as concentrate grade, tailing grade and magnetic iron loss are better than those of the latter and what's more, it is more adaptable to the feed condition change. Therefore, it is of good popularization value.
