Overband Magnet

The First Line of Defense in Metal Recovery

Overband magnets serve as the primary ferrous metal separation system in shredding operations, hovering like sentinels above conveyor belts to extract valuable steel components from mixed material streams. These self-cleaning magnetic systems combine brute magnetic force with intelligent design to maximize metal recovery while maintaining continuous material flow.

Engineering for Maximum Ferrous Capture

Modern overband magnets employ powerful rare-earth neodymium magnets arranged in deep magnetic circuits to generate intense magnetic fields. The systems feature heavy-duty rubber conveyor belts that continuously remove captured metals, with adjustable suspension heights allowing operators to optimize separation for different material depths. Advanced models incorporate electromagnetic designs with variable intensity controls for processing challenging material mixes.

Operational Performance in Shredding Lines

Positioned after primary shredding, overband magnets demonstrate remarkable efficiency, typically recovering 95-98% of ferrous metals from mixed scrap. Their suspended design allows installation over existing conveyors without disrupting material flow, while the self-cleaning mechanism discharges captured metals into separate collection chutes. The systems operate continuously without downtime, processing thousands of tons of material with minimal supervision.

Maintenance for Peak Magnetic Performance

Regular maintenance ensures consistent metal recovery rates. Daily inspections should verify proper belt tracking and tension, while monthly bearing lubrication prevents premature wear. Magnet strength should be tested quarterly using a gaussmeter, with demagnetized units requiring immediate replacement. Many modern systems feature integrated monitoring that alerts operators to declining performance before it impacts recovery rates.

Strategic Integration in Recycling Systems

When positioned correctly in the processing line - typically after size reduction but before fine sorting - overband magnets provide the first critical separation step. Their operation significantly reduces wear on downstream equipment by removing abrasive ferrous metals early in the process, while simultaneously increasing the value of recovered non-ferrous materials by improving purity.
