A permanent magnet iron remover utilizes the characteristic of magnets adsorbing iron products to achieve iron removal within an effective range. The interior of the permanent magnet iron remover is composed of a composite magnetic system made of special permanent magnets such as neodymium iron boron with high coercivity and high remanence. When the permanent magnet adsorbs a large amount of ferromagnetic material, it can be manually removed with a non-magnetic scraper or gloves, which is suitable for continuous work and situations with low iron content.
