Magnetic Separator Air-Gap Explained

Bunting Air gap explained

The ‘Air Gap’ plays a key role in the performance of a Magnetic Separator.  In all magnetic separators, there is a gap between the magnet material or electromagnetic coil and the targeted particle.  This ‘air-gap’ could be actual air or a non-metallic material such as stainless-steel or a rubber belt. When assessing an application, our…

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,…

What is an Axial and Radial Magnetic Field?

Radial Magnetic Field Bunting Magnetics

Rotary Magnetic Separators, such as the Drum Magnet and Pulley Magnet, are designed with a specific type of magnetic field.  The type of magnetic field is considered when looking at any application and when deciding which design will achieve a customer’s separation objective. For these rotary designs of magnetic separator, there are two types of magnetic…

3 Metal Parts Contaminating Plastic Waste

3 metal parts contaminating plastic waste

Recycling plastic waste is challenging at the best of times. However, when contaminated with ferrous metals, recycling is hindered by equipment damage, production downtime and poor end product quality. Thankfully, installing the optimum magnetic separator ensures that such ferrous metal contamination is removed. In this article we look at three examples of ferrous metal contamination…

Metal Removal when Recycling Rubber Tyres

Metal separation - Rubber crumb

Successfully removing metal from rubber (originating from the metal wire in a tyre) when recycling tyres is critical, especially as rogue metal can cause injury to horses and children who run and play on the recovered rubber crumb.  Although each tyre recycling plant is different, here is a guide to the common types and location…

Detecting and Removing Tramp Metal from Conveyors

metal detector by bunting

The process of quarrying aggregate and mining ore often results in the introduction of tramp metal.  The effective detection and removal of this tramp metal is critical to prevent damage to crushers, screens and conveyors, and is achieved using metal detectors and magnetic separators. The design of metal detector or magnetic separator is dependent upon…
