The Drum Magnet by Bunting is a high-efficiency magnetic separator designed to remove ferrous metal contaminants from a variety of product streams. This separator ensures product purity and protects processing equipment from potential damage.

These magnets continuously capture and discharge ferrous contaminants without interrupting product flow. As material passes over the drum, magnetic particles are attracted and held to the drum’s surface (radial pole design), while non-magnetic material flows freely to the discharge point. Cleats on the drum assist in sweeping the captured metal out of the magnetic field, ensuring continuous self-cleaning operation.

By integrating the Drum Magnet into your processing line, you enhance product quality, ensure compliance with industry standards, and extend the lifespan of your equipment.

Continuous, Automated Operation Eliminates the need for manual separation or downtime—ideal for high-volume, 24/7 operations. Reduced Equipment Wear and Maintenance By removing ferrous metals upstream, drum magnets protect shredders, grinders, screens, and other downstream equipment from damage and costly repairs. Increased Product Purity Ensures cleaner output by effectively separating even weakly magnetic or fine ferrous contaminants. Energy-Free Magnetic Power Fully permanent magnet systems require no electricity to operate, lowering operating costs and simplifying integration. Flexible for Any Application Available in a range of diameters, widths, magnetic strengths, and field configurations (axial or radial) to match your specific material and flow characteristics. Low Maintenance and Long Lifespan With no moving internal parts and wear-resistant components, Bunting Drum Magnets offer years of reliable, maintenance-light service. Designed for Harsh Environments Built tough to handle abrasive, dusty, or moisture-prone materials commonly found in recycling, mining, and plastics processing environments. Precision Separation with Adjustable Splitter Customize the split point between magnetic and non-magnetic fractions for more efficient recovery and minimal product loss.
