Electromagnetic Slurry Magnetic Separator

Introduction: Electromagnetic slurry magnetic separator is the latest magnetic separation product developed by Guote Mining Equipment. Its background magnetic field can reach up to 2.2 Tesla, with a large magnetic field gradient, and a variety of special magnetic conductive stainless steel media are available to meet the beneficiation needs of different regions and different types of minerals.

Working process: In the early stage of beneficiation, the excitation coil is energized with direct current to form an induction magnetic field of up to 22000GS on the surface of the magnetic medium in the separation area. The slurry containing impurities is quantitatively fed into the lower magnetic yoke through the bottom feed pipe by a slurry pump equipped with a variable frequency speed regulating motor. After the slurry is evenly dispersed, it enters the magnetic medium separation area through the pores of the lower magnetic yoke. The magnetic particles in the slurry are firmly adsorbed on the surface of the magnetic medium, and the non-magnetic particles pass through the magnetic medium and are discharged from the mine mouth through the pores of the upper magnetic yoke. After the beneficiation process has been running for a period of time, a large number of magnetic particles are adsorbed on the magnetic medium, and the control system automatically enters the return ore process. When the excitation coil is continuously energized, the feed valve is first closed, and then the return valve is opened. At this time, the slurry remaining in the cavity flows back to the original ore pool. After the slurry in the chamber is completely emptied, the return valve is closed and the control system automatically enters the flushing process. First, the excitation coil is powered off, the magnetic medium loses its magnetic field, and the adsorption force on the magnetic particles disappears. Then the tailings valve and the flushing valve are opened in turn, and the magnetic medium is repeatedly flushed with positive and negative high-pressure flushing water and pulse high-pressure gas, 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, the flushing valve and the tailings valve are closed in turn, and the flushing process ends. The control system automatically starts the magnetic particle sorting process, and then the equipment starts a new round of process cycle.
