Modified ToughFlex® Belt for Overband Magnets

Bunting has joined forces with Smiley Monroe to modify a ToughFlex® belt for Overband Magnets.  The new belt is more resistant to excessive wear in arduous working conditions. Overband Magnets have a permanent or electromagnetic block mounted between two pulleys over which continuously runs a cleaning belt.  In operation, the Overband Magnet is suspended over…

Single, Twin and Tri Pole Overband Magnet Development

Overband Magnet

Bunting has developed three designs of Permanent Crossbelt Overband Magnet (PCB), with different magnetic polarity, to suit an ever-expanding range of applications.  Overband Magnets are mounted over conveyors to separate ferrous metal from non-magnetic material and are commonly used in industries including mining, quarrying, recycling, and wood. The magnetic field of a Permanent Crossbelt Overband…

Magnetic Metal Free Areas under Overband Magnets

A common question asked when a client is installing an Overband Magnet or Suspension Magnet is whether the conveyor idlers, frame and housing could become magnetically induced. When installed suspended above a conveyor, the Overband Magnet and Suspension Magnet work by projecting a magnetic field down and through material transported on a conveyor.  This magnetic…

ATEX 22 Rated Electro Overband Magnets

ATEX 22 rated Electro Overband Magnet

The latest ATEX 22 rated Electro Overband Magnet, designed and built by Bunting, is destined for installation in a UK biomass plant.  The nature of the waste wood means that the storage and transportation areas within the plant are classified as ATEX Zone 22, where an atmosphere of air and flammable substances, in the form…

Benefits of the Overband Magnet Armoured Belt

Overband Magnet Armoured Belt

The highest wear part on an Overband Magnet is the belt that transfers the separated metal away from the conveyor and into a collection area.  In order to reduce such wear, Bunting developed a special lightweight armouring for the rubber belt. The Overband Magnet Armoured Belt is in operation in recycling, mining, quarrying and bulk…

Permanent Overband Magnet Selection Criteria

Permanent Overband Magnets are commonplace in most mines and quarries, removing tramp ferrous metal and protecting crushers, screens and conveyors against damage. Overband Magnets are also widely used in recycling, recovering ferrous metals and protecting shredders against metal damage.  However, there are many different designs of Permanent Overband Magnet, developed to suit specific applications.  Understanding…

6-Year-Old Electro Overband Magnet Refurbishment

6-Year-Old Electro Overband Magnet Refurbishment

Repair and refurbishment convert a well-used, functional magnetic separator into almost new, further extending the life of the equipment.  One of Bunting’s latest repair and refurbishment projects involved a 6-year-old Electro Overband Magnet. The oil-cooled Electro Overband Magnet model 155 OCW 45 CB separates tramp ferrous metal from biomass pellets in a bulk handling terminal…

Permanent or Electro Overband Magnet Selection

Overband magnets

The Overband Magnet is one of the most commonly used magnetic separators.  Different designs are used in nearly all process industries and especially in mining, quarrying, recycling, and bulk handling applications. In operation, an Overband Magnet (or Suspension Magnet) sits above a conveyor carrying material.  As the material passes under the magnet, ferrous metal is…
