Do you know the reason for the large magnetic reduction of the suspended permanent magnet separator

When using the suspended permanent magnet separator, we must first understand the concept of permanent magnets in permanent magnet separators. The so-called permanent magnets are literally understood as magnetic eternal, so why is the use of suspended permanent magnet separators? There will be a large reduction in magnetic force, or even degaussing. Here is a simple introduction from Henderson Magneto

In fact, there is a problem of using combativeness. For example, solar power generation does not have electricity from the sun. For example, if the light energy exchanger is aging, it will not be able to generate electricity normally. Therefore, the hanging permanent magnet iron remover also has the same reason, the magnet is intact, but the transmission device that transmits the magnetic force is aged if it is used for a long time without knowing the protection, or the magnet is installed in the process of disassembling, the two stages of the magnet are reversed. It will lead to mutual exclusion and magnetic consumption. If there is a phenomenon of degaussing of the suspended permanent magnet separator, there is no need to worry about it. Check the installation process for any problems. Generally, the suspended permanent magnet separator is not as easy as it is.
