Overband Magnets

Remove Tramp Iron. Protect Equipment. Maintain Throughput.

 

Bunting® Overband Magnets, also called Crossbelt Magnets, are powerful, self-cleaning magnetic separators designed to remove tramp ferrous metals from conveyed materials. Installed crossbelt or inline, these units protect shredders, crushers, and other downstream equipment from costly damage while maintaining uninterrupted production flow. Available in permanent or electromagnetic configurations, Bunting Overband Magnets are trusted in mining, aggregates, recycling, and heavy industrial applications worldwide.

Overband Magnet Models

Permanent Overband Magnet (PCB)

The most economical and low-maintenance option for continuous tramp metal separation. These self-cleaning magnets use high-strength permanent magnet blocks to extract ferrous metal from conveyed materials.

Ideal for:

  • Mobile crushers and screeners
  • Lightweight ferrous recovery
  • Construction and demolition recycling

Key Features:

  • No power required for magnetic field
  • Cleated self-cleaning belt system
  • Available in to suit working gaps up to 400mm (16")

ElectroMax Air-Cooled Overband Magnet (EMAX)

This high-intensity electromagnetic separator is 185% stronger and 25% lighter than conventional permanent overband (crossbelt) magnets. Ideal where weight, space, and enhanced metal separation are critical.

Ideal for:

  • Mobile recycling and crusher systems
  • Mining, quarrying and bulk aggregate systems
  • Removal of challenging ferrous metal such as digger teeth

Key Features:

  • Powerful electromagnetic coil
  • Air-cooled design, no oil present
  • Highest magnetic power to weight ratio of any overband magnet
  • Optional armored belt
  • Supplied with air or oil cooled transformer rectifiers

Oil-Cooled Electromagnetic Overband Magnet (OCW)

Engineered for heavy-duty applications where maximum separation strength is essential. Oil-cooled electromagnets achieve deep field penetration for removal of large tramp metal pieces from deep burden depths.

Ideal for:

  • Mining, quarrying, and bulk aggregate
  • Bulk handling terminals and waste to energy plants
  • Deep burden depths and high-speed belts

Key Features:

  • Rugged construction with armored belt options
  • Works at increased suspension heights up to 800mm (32")
  • Suitable for belt widths up to 2400mm (96")
  • ATEX rated models available
