Description

Technical Field

[0001] The utility model relates to the technical field of iron removers, in particular to an electromagnetic iron remover for powder materials. Background Art

[0002] A powder iron remover is a device used to remove ferromagnetic impurities from powdered materials. It mainly separates ferromagnetic substances from powdered materials through magnetic force. Powder iron removers are usually made of magnets or magnetic materials and have strong magnetism. Its working principle is to establish a strong magnetic field to attract and collect ferromagnetic impurities in powdered materials. When the powder passes through the iron remover, the ferromagnetic impurities will be adsorbed on the magnet or magnetic material and then separated from the material flow. Powder iron removers can be widely used in the production process of powdered materials, such as food processing, chemical, pharmaceutical, plastic, mineral and other industries. It can effectively improve the quality of products and prevent ferromagnetic impurities from damaging equipment or products. It also helps to comply with relevant quality and hygiene standards.
