Self-Cleaning Hump Magnet

       The equipment features high-performance NdFeB permanent magnets or rare-earth magnetic materials inside, generating a high-gradient strong magnetic field (with a surface magnetic field strength of 10,000–15,000 gauss). This effectively adsorbs fine ferrous contaminants such as iron chips, iron powder, and rust, thereby enhancing material purity and ensuring the safe operation of downstream equipment. As the material passes through the hump-shaped channel, it continuously changes direction under gravity or airflow, making full contact with the dual-sided magnetic plates to achieve multiple captures and improve ferrous contaminant removal efficiency. Iron impurities adsorbed on the magnetic plates are automatically scraped off and discharged by a pneumatic system driving a scraper or oscillating arm mechanism. After cleaning, the equipment automatically resets and resumes continuous operation.

Features and Advantages

• Fully Automatic Cleaning System: Utilizes a pneumatically driven scraper or oscillating-arm mechanism for automatic iron removal, eliminating the need for manual disassembly and suitable for continuous production environments.
• Hump‑Shaped Dual‑Plate Design for High‑Efficiency Ferrous Removal: The material changes flow direction multiple times within the channel, increasing its exposure to the magnetic field and enhancing the capture of fine ferrous impurities.
• High Magnetic Field Strength for Thorough Iron Removal: Equipped with NdFeB permanent magnets, the magnetic field strength reaches 10,000–15,000 gauss, effectively removing micrometer‑sized ferromagnetic particles.
• Stable Operation and Broad Adaptability: Suitable for dry powders, granules, and free‑falling materials, and can be installed at hopper outlets or in vertical/inclined pipelines.
• Corrosion‑Resistant Structural Design: The housing is made of 304 or 316L stainless steel, meeting the requirements of the food, pharmaceutical, and chemical industries.
