Description

Electromagnetic slurry high-gradient magnetic separator is applicable to the iron removal and purification of non-metallic minerals such as potassium and sodium feldspar, quartz sand, kaolin, nepheline, fluorite, kyanite and sillimanite, as well as the separation of fine-grained metallic minerals. It is particularly effective in purifying fine-grained non-metallic minerals. When used in conjunction with the high-gradient strong magnetic machine of the vertical ring, this equipment can produce high-quality non-metallic concentrate.

Structure drawing

In the initial stage of mineral processing, a direct current is passed through the excitation coil, creating an induced magnetic field with a force as high as 22,000 Gs on the surface of the magnetic medium in the separation zone. The slurry containing impurities is quantitatively fed into the lower magnetic yoke through the bottom feed pipe by the slurry pump equipped with a variable frequency speed-regulating motor. After being uniformly dispersed, the slurry enters the magnetic medium separation zone through the pores of the lower magnetic yoke. The magnetic particles in the pulp are firmly adsorbed on the surface of the magnetic medium, while the non-magnetic particles pass through the magnetic medium and are discharged from the ore mouth through the pores of the upper magnetic yoke. After the beneficiation process has been in operation for a period of time, a large number of magnetic particles adhere to the magnetic medium, and the control system automatically enters the return ore process. When the excitation coil is continuously energized, first close the feed valve, then open the return valve. At this time, the remaining pulp in the cavity flows back to the original ore pool. After the pulp in the cavity is completely drained, close the return material valve and the control system will automatically enter the flushing process. Firstly, when the excitation coil is de-energized, the magnetic medium loses its magnetic field, and the adsorption force on magnetic particles disappears. Then, open the tailings valve and the flushing valve in sequence. Use positive and negative high-pressure flushing water and pulse high-pressure gas to repeatedly flush the magnetic medium, so that the magnetic particles adsorbed on the magnetic medium are thoroughly flushed off and discharged into the magnetic particle tank. When the magnetic medium is flushed out, the flushing valve and the tailings valve close in sequence, and the flushing process is thus completed. The control system automatically initiates the magnetic particle sorting process, and then the equipment begins a new round of process cycle.
