Magnetic Separator
1. Application
Magnetic separator is application for to wet magnetic separator magnetic, magnetic pyrite, roasted ore and ilmenite with the size less than 3mm. And it also can be used to remove iron for coal,non-metal mineral and building materials etc. Magnetic system is made by compounding the superior ferrite materials with rare earth cobalt-magnet. The magnetic introduction is 100-600mT. According to client's requirements, we can provide clients with fair current, half fair current and counter current magnetic choice with different magnetic induction. It has the advantages: simple structure, big processing capacity, easy to operate and maintain.
Magnetic separator is divided into wet and dry magnetic separator.
2. Working principle
The mineral slurry flows into the cell through box feeder, the mineral particle is loose under the function of water flow of feeder water pipe when they flow into the cell. Affected by magnetic field, the magnetic particle swarm together and form magnetic cluster or chain. With the magnetism of mineral slurry, the magnetic cluster or chain moves toward the magnetic pole, and is absorbed to the cylinder. Because of the polarity of magnetic pole, the revolving directions alternate constantly, and remain fixed when it is working. When the magnetic cluster and chain go round and round along with the cylinder, the mingled gangue and other non-magnetic ore fall down due to the mixing phenomena produced by alternation of magnetic poles, and it is concentrate that is absorbed to the cylinder surface. The concentrate moves to the end of magnetic system where the magnetism is weakest along with the revolving cylinder, and is discharged into concentrate tank by the current ejected by the discharging-ore pipe. The non-magnetic or weak magnetic remained are discharged along with the mineral slurry, and they are gangue.
