Wet-type permanent magnet composite magnetic separator

The utility model relates to a wet-type permanent magnet composite magnetic separator, belongs to mining machine sorting devices, and particularly relates to a permanent magnet roller-type magnetic separator. The wet-type permanent magnet composite magnetic separator comprises a weak field intensity roller-type magnetic separator body, a medium field intensity roller-type magnetic separator body and a high field intensity roller-type magnetic separator body; the weak field intensity roller-type magnetic separator body, the medium field intensity roller-type magnetic separator body and the high field intensity roller-type magnetic separator body are all fixed to a rack and driven by a driving system; the weak field intensity roller-type magnetic separator body is formed by a weak magnetic separation groove, a permanent magnetic pulley and a mine discharging water tube, and the medium field intensity roller-type magnetic separator body and the high field intensity roller-type magnetic separator body are each formed by a chute, a drain separator, a high-pressure flushing apparatus, a permanent magnet magnetic roller, a discharging brush and a magnetic separation groove. The wet-type permanent magnet composite magnetic separator has the advantages that a weak, medium and high field intensity magnetic separation composite structure is adopted, the wet-type permanent magnet composite magnetic separator is particularly suitable for nonmetal material pulp deironing with the concentration lower than 30%, iron impurities in different types can be removed in a batch mode, and interference of high magnetic impurities to the high field strength magnetic separator body is reduced; meanwhile, repeated attraction is avoided, device losses are reduced, and the iron removal effect is improved.
