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…
Read MoreSingle, Twin and Tri Pole Overband Magnet Development
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…
Read MoreMagnetic 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…
Read MoreBenefits of the 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…
Read MorePermanent 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…
Read MoreEddy Current Separator and ElectroMax Sales Growth in 2021
The demand for metal separators increased in 2021 on 2020, with exceptional growth in sales of both Eddy Current Separators and ElectroMax Overband and Suspension Magnets. Sales growth followed an expansion in representation in overseas markets and increasing manufacturing capacity at Bunting’s Redditch facility in the UK. At the Redditch manufacturing plant, Bunting specialise in…
Read MoreThe Crusher’s Arch Enemy – Tramp Metal
Crushing quarried aggregate is a key process stage of most quarries and when recycling demolition waste. Effectively protecting the crusher from rogue tramp metal damage prevents production losses and repair costs. The wide range of available crushing technology enables the production of optimally sized aggregate. Whereas Jaw and Gyratory designs commonly feature as primary crushers,…
Read More6-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…
Read MoreStronger ElectroMax-Plus Overband Magnet
The design objective of creating a more compact and powerful electromagnetic Overband Magnet led the Bunting engineering team to develop the ElectroMax-Plus. Electro Overband Magnets Electromagnetic Overband Magnets use an oil-cooled or air-cooled wire coil to generate a deep and strong magnetic field. The electromagnetic force radiates from a coil wound around a steel core…
Read MoreDemonstrating the ElectroMax Overband Magnet’s Power
The ElectroMax Overband Magnet has proved extremely popular since the launch in May 2019. Shipments average at over one ElectroMax per month with an increasing number of mobile plant, mining and recycling companies turning to the air-cooled ElectroMax Electro-Overband Magnet as a high-performance, lightweight option to the traditional Permanent Overband Magnet. Technical information: Overband Magnets…
