Sorting process of wet weak magnetic field permanent magnetic cylinder magnetic separator

The sorting process is (Fig. 1). After the slurry is fed into the tank body 3 (bottom tank) through the feeding tank 7, the ore is loosely fed into the feeding area of ​​the tank bottom under the action of the water flow to the mine spout pipe 6. . Due to the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a "magnet" or "magnetic flux", and are attracted to the magnetic pole by mechanical force such as gravity, and are attracted to the surface of the cylinder 1. Then turn up with the cylinder. Due to the alternating polarity of the magnetic system, magnetic agitation occurs in the ore particles to cause the mechanically mixed gangue to fall off, thereby improving the concentrate grade. The magnetic ore particles go to the weakest point along the edge of the magnetic system with the cylinder. Under the action of the flushing water jet discharged from the unloading water pipe 8, it is discharged into the concentrate tank. The non-magnetic or weak magnetic ore particles are discharged from the tailings hole of the bottom plate 9 into the tailings tube under the action of the slurry flowing rapidly in the tank.
