The high gradient high intensity magnetic separator is a rotary vertical rotating magnetic separator, which is suitable for the beneficiation of weakly magnetic minerals and the iron removal and purification of non-metallic minerals.
After the ore slurry flows into the tank through the ore feeding box, the ore particles enter the feed area of the tank in a loose state under the action of the water flow of the ore feeding spout. Under the action of the magnetic field, the magnetic particles gather magnetically to form "magnetic clusters" or "magnetic chains", "magnetic clusters" or "magnetic clusters"The magnetic chain "is affected by the magnetic force in the pulp, moves towards the magnetic pole, and is adsorbed on the cylinder. Because the polarity of the magnetic pole is alternately arranged along the rotating direction of the cylinder, and is fixed during operation, when the" magnetic cluster "or" magnetic chain "rotates with the cylinder, the magnetic stirring phenomenon is generated due to the magnetic pole alternation, and is mixed in the" magnetic cluster "or"The non-magnetic minerals such as gangue in the magnetic chain fall off during turning, and the "magnetic cluster" or "magnetic lotus" finally absorbed on the surface of the cylinder is the concentrate. The concentrate turns to the weakest magnetic force at the edge of the magnetic system along with the cylinder, and is discharged into the concentrate tank under the action of the washing water jet from the ore unloading pipe. The non-magnetic or weakly magnetic minerals are left in the pulp and discharged out of the tank with the pulp, which is the tailings

Beneficiation of weakly magnetic minerals, such as hematite, limonite, ilmenite, wolframite, tantalum niobium ore, etc
Iron removal and purification of non-metallic ores, such as quartz, feldspar, nepheline, fluorite, sillimanite, lithium pyroxene, kaolin, etc

The problems of rotary vertical rotary and recoil concentrate, flat ring high intensity magnetic separation and magnetic medium blockage are unsolved technical problems at home and abroad for decadesSLon magnetic separator adopts rotary ring vertical rotation mode. For each group of magnetic media, the direction of washing concentrate is opposite to the direction of ore feeding. Coarse particles can be washed out without passing through the magnetic media stack, thus effectively preventing the blockage of magnetic media
