The Crusher’s Arch Enemy – Tramp Metal

The crushers 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,…

Electromagnetic Filters for Ceramics

Electromagnetic Filters for Ceramics

Since the first ceramics were produced, iron and iron-bearing minerals have caused defects.  The problematic minerals occur naturally in the raw materials, with additional fine iron accidentally introduced during transportation, storage or processing. Effective removal often involves several stages of magnetic separation.  However, the introduction of High-Intensity Electromagnetic Filters proved ground-breaking in terms of removing…

Recycling Growth Dependent on Technology

Recycling Growth dependent on technology

Annual events such as the UK’s Recycling Week, the Global Recycling Day and Earth Day provide the perfect platform for reflection and planning.  Successful and extensive recycling reduces the pressure on the planet’s finite resources, whilst also providing desperately needed environmental protection.  Many experts predict that the failure to radically change the way waste is…

Magnetic Properties of Ceramic Minerals

Bunting Magnetics Bauma

Magnetic minerals and fine iron have plagued ceramic producers since the first glazed pot was produced many thousands of years ago.  Early ceramicists adopted elaborate and colourful patterns to cover any imperfections caused by such contamination.  Over time, the demand for white or single coloured ceramic products increased, making disguising any imperfection increasingly difficult. Ceramic…

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…

Wet High Intensity Magnetic Separation Testing

Wet High Intensity Magnetic Separation Testing

The electromagnetic laboratory-scale Wet High Intensity Magnetic Separator (WHIMS) removes fine magnetics and para-magnetics from mineral slurries.  Handling minerals in a slurry or suspension is preferable for many processors, especially when beneficiation involves wet processing.  Additionally, a wet process often produces a better separation for very fine materials. In this educational video, Professor Neil Rowson…

Metal Recovery from WEEE and Cable

Cable Recycling diagram

There is a wealth of valuable metals present in WEEE (Waste of Electrical and Electronic Equipment) and cables. However, the recovery is often difficult due to the small particle size range and variable nature of the metals. With the development and launch of the ElectroStatic Separator [in 2020], Bunting now provides a complete multi-stage metal…

Ensuring In-House Plastic Recycling Purity

Bunting-Plastics Internal Recycling

When re-processing in-house plastic rejects and waste, the purity of the final recycled plastic mix must be equal or at least very close to the original raw material.  Whether the re-processed plastic is for in-house use or as regrind for resale, the removal of any metal contamination is critical. Successful removal of metal contamination from…

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…
