When the permanent magnet sucker closed permanent magnetic separator price, no magnetic force. The so-called strong permanent magnet sucker closed magnetic circuit means is blocked. There is no pole. When the magnetic circuit is not closed, but in the open state, the permanent magnet sucker thrown on both ends of the pole permanent magnet separator surface characteristics, namely N and S poles. The magnet poles to produce a magnetic field in its vicinity. The magnetic field generated by the magnetic poles, always pole inside the magnet, the direction of the magnetic field in the opposite direction from the N pole to the S, it played the role of demagnetization of permanent magnet separator, so called demagnetizing field, have demagnetization of permanent magnet sucker function. The size of the demagnetizing factor of the magnet shape and size related. Applicable to coal ports, large thermal power plants, coal mines, mining, building materials and other requirements for the removal of iron especially high places, permanent magnetic separator manufacturers can work normally in the dust, moisture, sea salt spray corrosion and serious adverse environment, oil cooling is the world's most commonly used electromagnetic separator cooling mode, the product in accordance with the standards of similar products in Germany and the USA design, the use of evaporative cooling iron production process, which can effectively prevent oil leakage, stable product quality, mature, and reliable.
