What is the Principle of Magnetic Separator?

Magnetic separator is a kind of equipment that separates impurities by magnetic force. It takes advantage of the material's response to magnetic fields to separate magnetic impurities from non-magnetic materials.

The basic principle of the magnetic separator is to pass the granular material through the area of the magnetic field, under the action of the magnetic field, the magnetic particles will be attracted by the magnetic field, while the non-magnetic particles will not be affected.By adjusting the strength and direction of the magnetic field, the separation effect of the particles can be controlled.

Magnetic Field area and Conveying Device

Specifically, the magnetic separator mainly includes a magnetic field area and a conveying device. The magnetic field region is usually made up of magnetic materials, and by applying an electric current or a permanent magnet, a magnetic field is generated.

The conveying device conveys the material from the inlet to the magnetic field area, and moves the material along the magnetic field area by adjusting the conveying speed and vibration force.

When the material passes through the magnetic field region, the magnetic particles are attracted by the magnetic field and are adsorbed to the surface of the magnetic field region.

Non-magnetic particles are not affected and continue to move along the magnetic field.

Finally, the magnetic particles are collected from the magnetic field area by the conveyor, while the non-magnetic particles are discharged from the magnetic field area.

Conclusion

Overall, magnetic separators achieve the separation of magnetic and non-magnetic particles by taking advantage of the material's response to magnetic fields. It has a wide range of applications in ore treatment, waste treatment, and other fields.
