Do not ignore the influence of material temperature on the Overband Magnet separator

The magnetic source of the Overband Magnet separator is a high-performance permanent magnet material, which does not rely on electric energy excitation during the working process, and has a remarkable energy-saving effect, and the permanent magnet separator does not need a control circuit, and the operation is reliable and the failure rate is low. Small size and easy to install, it has become an ideal iron remover device for many users. However, in use, the magnetic force of the Overband Magnet separator is also affected by some factors. The temperature of the material is a key aspect. When the temperature of the material is too high, the magnetic force of the Overband Magnet separator may be attenuated or even lost.
The permanent magnets used in the current Overband Magnet separator are mostly NdFeB materials. Although the Curie temperature of NdFeB is between 320 °C and 380 °C, the molecular structure of NdFeB is already in the process of heating. Start to change, and the magnetic force will retreat after reaching the theoretical Curie temperature. The temperature of the NdFeB material tested was 100 degrees Celsius. When heated to about 100 degrees Celsius, the magnetic force began to drop, but the speed was not fast. After reaching 150 degrees Celsius, the speed of magnetic force decreased significantly. At 150 degrees Celsius, the magnetic force would be basically 20 minutes. Retreat. After removing the magnetic NdFeB, it can only reach about 50% of the original after magnetization, and the surface will appear black and oxidized.
