When the permanent magnet sucker closed, no magnetic force. The so-called strong permanent magnet sucker closed magnetic circuit means is blocked. There is no pole. When the permanent magnetic separator magnetic circuit is not closed, but in the open state, the permanent magnet sucker on the end faces of appearing pole permanent magnet separator manufacturers, namely N and S poles. The magnet poles to produce a magnetic field in its vicinity. Permanent magnetic separator magnetic field strength generated from the N pole to the S always pole of the inner magnet, the direction of the magnetic field in the opposite direction, from its permanent separator specifications demagnetization effect, so called demagnetizing field , has a permanent magnet sucker demagnetization function. The size of the demagnetizing factor of the magnet shape and size related. Dry Magnetic Separator is a continuous addition of iron powder for magnetic separation equipment, the internal structure of the latest advanced technology from Japan, magnetic system with super king NdFeB permanent magnet materials, with a strong magnetic field, suction, except Rail rate, energy saving and easy to maintain, easy to use features. Adjust the feed rate of the size of the aircraft, for different particle size requirements. Our products are widely used in glass, ceramics, cement, abrasives, refractory, carbon black, food, feed, chemicals, non-metallic mineral processing and other industries.
