what is magnetic separation in Quartz?

 

Strong excitation, that is, the instantaneous voltage of the power supply reaches 290V, the duration is about 6S, and then returns to the weak excitation 220V. The strong excitation is caused by the high excitation voltage, and the magnetic field will be larger than the weak magnetic field. Once the material is sucked up, Go back to the weak magnetic field and carry out the iron removal work. Generally, the strong excitation is used in the iron remover, and the conventional use is widely used in the suction and scrap steel. . . . The auxiliary excitation should not exist in the iron remover. The secondary excitation is called reverse degaussing. It can eliminate the magnetic field of the electromagnet in three seconds. If there is no auxiliary excitation, the working efficiency will be much slower. It is usually used on the electromagnet to quickly absorb and discharge materials, which is very efficient.
