◆ Product Introduction.

GTDZ series electromagnetic slurry high gradient magnetic separator is a new type of magnetic separation product developed by our company. The background magnetic field reaches 1.5T, the magnetic field gradient is large, and a variety of magnetic stainless steel media can be selected, which is suitable for the beneficiation needs of different regions and different types of minerals.

◆ Advantage Features.

1.Unique electromagnetic coil design and efficient cooling method. The excitation coil of the electromagnetic slurry high gradient magnetic separator is cooled by fully sealed cooling oil. The external high-efficiency heat exchanger performs oil-water heat exchange to achieve oil-water composite cooling, fast cooling speed, low temperature rise, and stable magnetic field.

2.The separation medium produces an extremely high magnetic field gradient, and the iron removal effect is better. The medium is made of special magnetic conductive stainless steel, which can produce an extremely high gradient magnetic field under the excitation of the background magnetic field. It has a strong adsorption effect on low-content weak magnetic impurities, and the iron removal effect is better.

3.Fully automatic operation, low operation and maintenance costs. The working process of the equipment is controlled by an automated program, which can realize unattended fully automatic operation, reducing operation and maintenance costs.

4.High-pressure water forward and reverse flushing, clean iron removal, no residue. When the equipment removes iron, high-pressure water is used to clean the medium and unload the iron cleanly. The cleaning time can be set according to different minerals and different stages of iron removal. Improve processing efficiency.

◆ Working principle.

At the beginning of the mineral processing process, the excitation coil is powered by direct current, and an induction magnetic field of up to 20000GS is formed on the surface of the magnetic medium in the separation area. The slurry containing magnetic impurities is quantitatively fed into the lower magnetic yoke through the bottom feeding pipeline through the slurry pump equipped with a variable frequency speed regulating motor. After being 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 concentrate particles pass through the magnetic medium and are discharged from the concentrate port through the pores of the upper magnetic yoke. After the mineral processing process has been running for a period of time, a large number of magnetic impurity particles are adsorbed in the magnetic medium, and the control system automatically enters the return process. When the excitation coil is continuously energized, first, the feed valve is closed, and then the return valve is opened. At this time, the slurry left in the cavity flows back to the original ore pool. After the slurry in the cavity is completely emptied, the return valve is closed, and the control system automatically enters the flushing process. First, the excitation coil is powered off, and the magnetic medium loses its magnetic field, and its adsorption force on magnetic impurity particles disappears. Then, the tailings valve and the flushing valve are opened in turn, and the positive and negative high-pressure flushing water and pulse high-pressure gas are used to repeatedly flush the magnetic medium, so that the magnetic impurity particles adsorbed on the magnetic medium are completely flushed and discharged by the tailings valve. When the magnetic medium is completely flushed, the flushing valve and the tailings valve are closed in turn, and the flushing process ends here. The control system automatically starts the impurity removal process, and then the equipment starts a new round of process cycle.
