Permanent magnet high gradient magnetic separator

The utility model discloses a permanent-magnetic high-gradient magnetic extractor, which comprises a vertically allocated separating ring and parts of the separating ring, such as a driving mechanism, a permanent-magnetic magnetic system, a non-magnetic mineral discharging box and the like, and a pulse mechanism is allocated in the non-magnetic mineral discharging box. The permanent-magnetic magnetic system comprises an upper portion and a lower portion, which forms a closed magnetism-gathering magnetic system through encircling the separating ring, and separating medium in the separating ring generates the high field gradient. An ore pulp channel is further arranged in a lower magnetic system. The utility model has the advantages that the energy sources are saved, the separating efficiency is high, an electromagnetic high-gradient magnetic extractor can be replaced, and the magnetic extractor can be effectively used for the wet-type separation between granule weakly-magnetic minerals and nonmagnetic minerals.
