Application Scope

This dedicated permanent magnetic drum iron remover for air chutes is used to remove ferrous impurities from materials conveyed by air chutes. It is connected to the air chute via mounting flanges. The permanent magnetic drum inside the protective cover rotates under the drive of the driving unit. When materials pass through, ferrous impurities are attracted by the drum and transported to the scraper assembly along with drum rotation, then scraped off and collected to complete iron removal. It can effectively protect downstream equipment and improve material quality.

Applicable industries: building materials, grain processing, feed, chemical industry, plastics, electric power, environmental protection, non-metallic mineral processing and other fields.

Working Principle

When materials in the air chute flow over the surface of the permanent magnetic drum, ferromagnetic particles are firmly adsorbed by the strong magnetic field generated by the built-in permanent magnets. As the drum rotates, the adsorbed ferromagnetic impurities are conveyed to the non-magnetic area. Under the combined action of gravity and scrapers, the impurities are stripped and collected, realizing the separation of ferromagnetic substances from non-ferromagnetic materials.

Technical Features

Automatic Iron Removal: The rotation of the permanent magnetic drum and the scraper assembly enable automatic iron removal and material collection. Frequent manual cleaning is not required, which boosts working efficiency.

Powerful Magnetism: High-performance permanent magnet materials such as neodymium iron boron are adopted as magnetic sources. Featuring strong magnetism and excellent anti-demagnetization performance, it can effectively adsorb both fine and large ferrous impurities.

Stable Operation: It is designed without excitation coils and rectifier control devices, so problems like temperature rise, insulation failure and voltage resistance do not occur. The equipment runs steadily with low maintenance cost.

Easy Installation: It can be detachably mounted on the support frame and transported separately. It is easy to install on various types of air chutes and features strong adaptability.
