The Self-Cleaning Hump Magnet by Mag Spring® is a high-efficiency magnetic separator designed to automatically remove tramp iron from free-fall abrasive bulk materials such as plastic pellets, grains, and powders. Built with NdFeB magnets up to 12,000 Gs, it ensures 99.9% iron removal efficiency while its wear-resistant construction extends service life even in harsh, continuous 24/7 operations. This self-cleaning design eliminates manual labor, reduces downtime, and protects downstream equipment from damage.
The Self-Cleaning Hump Magnet is ideal for gravity-fed or pneumatic conveying systems handling abrasive or hard materials. It’s widely used in:
Plastic Industry: For plastic pellets, regrind, and masterbatch purification
Food & Grain Processing: For sugar, flour, coffee, and grain separation lines
Chemical & Powder Production: For fine powder and granular materials
Mining & Mineral Processing: To remove ferrous particles from crushed ores or minerals
Recycling & Ceramics: For handling abrasive or high-wear materials
Feed & Fertilizer Production: For continuous tramp metal removal in high-volume lines
Each unit can be customized with reinforced wear plates and automatic cleaning mechanisms to suit specific process needs and abrasion levels.
The Self-Cleaning Hump Magnet by Mag Spring® is a high-performance magnetic separator engineered to remove tramp iron from free-fall or gravity-fed abrasive materials. Designed for continuous operation, it delivers up to 12,000 Gs of magnetic flux density using premium NdFeB magnets, ensuring 99.9% ferrous removal efficiency while minimizing downtime. Each unit uses high-energy NdFeB magnets compliant with IEC 60404 Magnetic Materials Standards ensuring consistent magnetic flux and long-term stability.
For industries dealing with hard or abrasive materials, traditional hump magnets suffer from rapid surface wear, reducing service life. Mag Spring® resolves this with a custom wear-resistant design, featuring reinforced liners and replaceable wear plates that dramatically extend lifespan under continuous 24/7 operation.
Manual cleaning is labor-intensive, unsafe, and interrupts production. The Self-Cleaning Hump Magnet automatically ejects trapped ferrous particles through pneumatic or motorized cleaning systems, allowing non-stop separation and protecting downstream machinery from metal damage.
The wear-resistant surface is specially built to withstand abrasive material impact, making it ideal for high-friction production lines.
