What should I do if the newly purchased belt magnetic separator has no magnetic force

The belt magnetic separator has a well-arranged magnetic circuit, a strong magnetic field and a high magnetic flux depth. It is suitable for screening iron products with a large thickness of the material layer. It is a high-performance special iron separator device for removing iron from magnetic materials. In the coal, cement, glass, ceramics, chemical, tobacco, mining and other industries, the belt magnetic separator is suitable for the removal of iron from crushers, conveyor belts, etc., and has a good effect in a variety of harsh environments. If the newly purchased belt magnetic separator removes no magnetic force, what is the reason? How to solve it?
1. Poor contact of the power supply causes the belt magnetic separator to be unable to be energized normally, so the magnetic power is completely absent.
2. The power control cabinet does not match the model of the belt magnetic separator, causing the magnetic coil of the belt magnetic separator to burn.
3, the newly purchased belt magnetic separator coil should not be damaged so quickly, if the above inspection or no magnetic force, you can contact the manufacturer of the iron remover, the technical staff to help find the reason why the magnetic force can not be generated.
