Temperature Effect on Magnetic Separators

Heat and Thermometer image

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 manufactured with high quality Neodymium Magnets are able to…

High-Intensity Magnetic Separators at Ceramitec

Iron-Specked_Ceramic_Tableware

High-intensity magnetic separators play a key role in the manufacture of ceramics and the processing of ceramic raw materials, as highlighted at Ceramitec 2022 on Bunting’s stand (on stand C1:511). Keeping Ceramics Iron-Free Fine iron and magnetic minerals cause defects in any ceramic product, whether that is tableware, sanitaryware, tiles or technical ceramics.  The iron…

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…

Five Magnetic Separator Myths

five Magnetic Separator Myths

Often ascertaining the best Magnetic Separator for any given application is not straightforward.  To complicate the decision-making process further, many companies supplying magnetic separators provide a wealth of information such as Gauss levels and the amount of metal that the Magnetic Separator can actually capture. Such details are often difficult to verify and may even be meaningless. In this…

Getting Metal Out of Beer

Getting Metal out of beer

Thankfully, it is very unlikely that you will ever find a piece of metal in your glass of beer.  However, when tramp metal (in the form of screws, nails, broken process plant, etc.) is accidentally introduced during the brewing process, it damages processing equipment and can even affect the taste of the beer.  In this…

Keeping Ceramic Tiles Iron Free

Keeping Tiles iron free

When fine iron and iron-bearing minerals contaminate the raw material used to produce ceramic tiles, the consequences are costly. Such iron contamination causes visual and structural defects as well as affecting the surface finish in terms of brightness and whiteness.  Tiles failing final quality checks are commonly returned for recycling. Those passing the initial quality…

Measuring Magnetic Separator Power

Bunting Magnetics Pull Test Kit

A Magnetic Separator attracts, captures and holds magnetic particles.  The magnetic strength needed to successfully separate such problematic ferrous metal contamination is commonly stated in a magnetic separator supplier’s quotation or specified in the tender.  This ‘Magnetic Strength’ is usually referenced in terms of ‘Gauss’, a unit of measurement.  However, as it is difficult to accurately measure…

Separating Fine Iron from Powders

Separating fine iron from powders

Effectively separating fine iron from dry powders is often challenging. Even the strongest magnetic separator may fail to successfully remove the magnetic particles. In order to find a successful solution, it is important to understand the way fine materials behave. Only then is it possible to determine the optimum method to cleanse a powder of…
