How to cool the Overband Magnet separator used for a long time

When the Overband Magnet separator is used for a long time, it needs to be cooled. How should the Overband Magnet separator that works for a long time cool down quickly? Let’s take a look at it together.
Continuous de-ironer work, synchronous belt conveyor work, its magnetic force is enough to separate the flow of coal of different types of iron, magnetic metal, etc., the iron is removed, the weight is as small as 0.1 kg, and the weight is as large as 50 kg. A disc type iron remover can remove the abandoned iron after the other disc type iron remover reaches the suction position; when the two belt type machines are simultaneously operated, each of the iron removers corresponds to one belt type machine, and the iron remover is timed. Abandoned iron, rated B = 800 mm, 250 mm high, the magnetic field strength should not be less than 1200 Gauss, after 48 hours, the magnetic pole surface high magnetic induction value (hot) 2800 Gauss.
The cooling method is: forced circulation oil-cooled type. In addition to the excitation method, the coil is completely sealed, the coil is immersed in the heat sink, and the design life is not less than 15-20 years. By forced circulation heat dissipation, heat dissipation theory and optimized heat dissipation structure are required to reduce the failure point of the entire structure.
