Bunting Develops High-Intensity Electromagnetic Wet Filter
Bunting has developed a new Electromagnetic Wet Filter with an ultra-high-intensity, background magnetic field (from 3,500 up to 10,000 Gauss). The magnetic separation technology separates fine iron and paramagnetic minerals from liquids and slurries and is used in the ceramics, mineral processing, and recycling industries, as well as cleaning wastewater in steel production and power…
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 MoreATEX 22 Rated Electro Overband Magnets
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…
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 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 MorePermanent or Electro Overband Magnet Selection
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…
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…
