Plastics and the Environment

The Necessity of a Global Strategy for Plastics Waste Since 1950, it is estimated that 8.3 million metric tonnes of virgin plastics have been produced.  Of this, 6.3 million metric tonnes has become waste, with 9% being recycled and 12% incinerated.  This leaves 79% that is accumulated in landfills or the natural environment. The report…

Temperature Effect on Rare Earth Magnetic Separators

Neodymium Magnet Damage From High Temperatures If a Neodymium Rare Earth Tube Magnet is put into a red-hot fire, then it would not be surprising if the magnetic properties are destroyed.  However, what if the same Tube Magnet is just exposed to steam being flushed through a pipeline system to clean the pipes? Tube Magnets…

Magnetic Separators Are Not Dangerous!??

9th of 10 Magnetic Separation Myths In school science, we learn about magnetism by playing with small permanent magnets.  It is fun, seeing how iron filings are affected by the magnetic field.  Our bodies are also constantly exposed to the Earth’s Magnetic Field. So how can Magnets be dangerous? In the 1980s, the concept of permanent…

You Can Block a Magnetic Field

8th of 10 Magnetic Separation Myths A common question asked by users of Magnets and Magnetic Separators is whether a Magnetic Field can be blocked in the same way that lead blocks radiation.  This can be an important issue when considering the location of a Magnetic Separator and whether it is near instrumentation, control panels,…

Is a Magnetic Field Uniform along the Surface of a Tube Magnet?

6th of 10 Magnetic Separator Myths On a typical Cartridge or Tube Magnet, the magnetic field on the surface is not even along the whole length.  As shown on the photograph, magnetically attracted materials agglomerate at specific points along the length.  So why is that? A Cartridge or Tube Magnetic Separator is constructed by placing…

The Highest Gauss Magnetic Separator is the Not Always the Strongest!

3rd of 10 Magnetic Separator Myths On a regular basis, we will receive an enquiry requesting a Magnetic Separator of a specific size.  However, it is only when the enquiry also requests a specific gauss figure that it all starts becoming a little complicated. Frequently, the gauss figure has been added with little understanding of the meaning…

Are all Rare Earth Magnetic Separators the Same?

2nd of 10 Magnetic Separator Myths A client has a metal contamination problem and needs to install the most suitable magnetic separation.  The metal is small and so they believe that a Magnetic Separator with Rare Earth Magnets is what they need as this produces the strongest magnetic field.  So he picks up the phone…

What is an Axial and Radial Magnetic Field?

Explaining Magnetic Separation Rotary Magnetic Separators, such as the Bunting Drum Magnet and Magnetic Separation Pulley, are designed with a specific type of magnetic field.  The type of magnetic field has to be considered when looking at any application and when deciding which design will achieve a customer’s separation objective. So what is an Axial or…

Should You Always Use the Strongest Magnet?

 1st of 10 Magnetic Separator Myths Strongest is always best, or is it?  Commonly, companies will call and request a quote for a Magnetic Separator with the strongest magnet.  But is that actually what they need? The strongest magnetic fields are produced by specialist Superconducting Magnets and are used in industrial and medical applications.  However,…
