New Teardrop Tube Magnet from Bunting

Teardrop Shaped Magnet Eliminates Product Bridging

Bunting has developed a new design of Rare Earth Tube Magnet for use in removing fine iron from dry powders.  The Teardrop Tube Magnet retains the high surface magnetic field of 12,000 gauss, but the shape prevents fine powder from building up on the surface.Bunting Teardrop Tube Magnet

Tube Magnets are used extensively in the processing industry to capture magnetic susceptible foreign bodies, including screws, nuts, bolts, and small iron shards, in both dry and wet applications.  Metal Contamination causes damage to delicate processing equipment, as well as affecting the end-quality and purity of the product.  Tube Magnets are commonly used in the form of a Grate Magnet, where several Tubes form a Magnetic Separation grid.

Rare Earth Magnets are constructed out of Neodymium Iron Boron magnet slugs.  These produce the highest permanent magnetic field and are used to separate very fine iron and weakly magnetic stainless steel from solids and liquids.

Even though the Rare Earth Tube Magnet is a tube with a spherical circumference, fine non-magnetic material often builds up on the upper-most point of the Tube.  Over time this ‘bridging’ can increase and ultimately cause a blockage.  The build-up always reduces the separation performance, increasing the likelihood of metal contamination continuing through the process.

The new Teardrop Magnet has the point of the tear orientated into the product flow.  The surface area on the point of the tear is very small and prevents fine powder collecting on the surface.  The powder then flows under gravity over the side of the Tube Magnet, with any magnetically susceptible materials attracted to the high magnetic force.  These magnetics migrate to the bottom of the Tube Magnet, where they are securely held away from the product flow.

The new Teardrop Tube Magnet is available as a single Tube or as part of a multi-Tube Grate Magnet assembly.

We Guarantee 100% Metal Separation

7th of 10 Magnetic Separator Myths

In the perfect world, installing a Magnetic Separator will enable 100% metal separation with 0% product loss.  However, is this even remotely possible?100-with-a-smile

Often as part of a project specification, there will be a question asking about the level and percentage of metal separation.  In some projects, the expected metal separation target is even stated.

The response from Magnetic Separator suppliers will include a statement regarding the level and percentage of Metal Separation, often without any qualification.  So what should the answer be?

There are a number of questions that need asking before the level of Metal Separation can be estimated and these include:

  1. What is the Metal Separation objective? Is it to remove problematic metal and protect processing equipment as when processing food, pharmaceuticals, or plastics?  Or is to recover as much metal as possible, which may be the objective in a recycling operation?
  2. How much product or non-metallic material can be lost? The non-metallic material might be the product or it could be the waste.  It is commonly found that higher Metal Separation rates are often accompanied by a higher loss of the non-metallic materials;
  3. What purity of end product is required? In recycling, the aim is to achieve recovery of metal, but at what point does the value of the recovered metal become affected by the level of contamination?  In the food and plastics industry, the final product quality is paramount;f33a6163
  4. How is the stated Metal Separation figure in terms of separation and/or purity monitored once the equipment is installed? Commonly, very high separation percentages are quoted by suppliers as it is well recognised that once the equipment has been installed the actual separation rate will never be checked;

Just asking these four questions enables a really good initial assessment of the application.  Then it is possible to make a recommendation in terms of the design of Magnetic Separator, and the mode of installation and operation.

Importantly, if a Metal Separation target is a key part of the contract, ensure that there is an agreed process to check the level of separation once the Magnetic Separator is installed.

With regards to the original statement, ‘We Guarantee 100% Metal Separation’, this is a claim made by only the brave or ill-advised.  Processing materials such as food, recyclables, minerals, aggregates, chemicals and plastics can be carefully controlled, but is always subject to variations that can affect any part of the process including the level of metal separation.  Even by installing multiple magnetic separators of different designs, achieving a 100% Metal Separation is simply a myth.

Bunting Metal Separators on Show at Arabplast 2017

Developing Export Business in the Middle East Plastics Sector

Bunting Magnetics Europe will be exhibiting at Arabplast 2017 in Dubai, UAE (8-10 January 2017) on stand 4D 145.  This is part of our continued export business development plan and is the first time we have exhibited in the Middle East.

ff-neo-4
Bunting FF Drawer Grate Magnet

Arabplast 2017 is the premier show in the Middle East for the Plastics, Petrochemicals and Rubber industries.  The show is held every 2 years at the Dubai World Trade Centre.

Dave Hills, Bunting’s Head of Sales, explained the reasons for exhibiting at Arabplast in 2017.

“In 2016, we have had great success in developing new overseas distribution channels and this has increased orders.  We identified the plastics sector in the Middle East as offering great opportunities.  The sector is rapidly developing and we believe that our products [metal separation equipment] are ideally suited to helping companies improve their production processes and product quality.  Arabplast offers us the ideal opportunity to introduce ourselves into the market.”

From the European manufacturing headquarters in the UK, Bunting supply a wide range of Magnetic Separators and Metal Detectors.  The Magnetic Separators are inserted into plastic processing lines to capture and remove magnetically susceptible metals like steel and work-hardened stainless steel.  Metal Detectors are used to identify and reject both ferrous and non-ferrous metal.  The two technologies are used in conjunction with each other at various stages within a plastics process.

We also supply Metal Separation equipment for plastics recycling.  In a typical plastics recycling process, the metal separation requirements are often more challenging.  The Eddy Current Separator is used to separate non-ferrous metals from shredded reclaimed plastic and is commonly incorporated into a Metal Separation Module with a high strength Drum Magnet as at Recapture Plastic in the UK.

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?

metal-contamination-on-magnets

A Cartridge or Tube Magnetic Separator is constructed by placing an alternating series of magnet slugs and steel discs inside a stainless steel tube.  Each magnet slug has a North and South pole and is inserted into the tube so that the South Pole faces another South pole and visa-versa.  When the magnet slugs are very strong, as in the case of the Bunting Cartridge Magnetic Separators which use high strength Neodymium Iron Boron or Rare Earth Magnets, the assembly requires a great deal of skill and knowledge.  In between each magnet slug is a steel disc which acts as a magnetic pole, intensifying the magnetic field.  As shown on the photograph below, the magnetic field is drawn into each steel pole positioned between each magnet slug, with magnetic field lines arcing from the North to the South Pole.

magnetics-on-a-tube-magnet

Any magnetically susceptible particle moving into the lines of magnetic field will be attracted to the point of highest intensity, which is at the nearest pole.  Hence why magnetically captured particles are then seen to agglomerate at specific points along the surface of a Cartridge or Tube Magnetic Separators.  They have been held at the point of the highest magnetic field, which is between the magnet slugs and actually on the steel pole piece.

Hence why a magnetic field is not uniform along the surface of a Magnetic Separator like the Tube Magnet.

Do Magnets Lose Strength Over Time

5th of 10 Magnetic Separator Myths

It is a question we frequently get asked:  When will the Magnetic Separator start losing its magnetic strength?  In normal operating conditions, a magnetic separator will not lose any magnetic strength.  However, there are occasions when other factors do affect the magnetic strength.  Such instances include:

  1. The use of bonded Rare Earth Magnets. These are lower in cost to manufacture and therefore cheaper to purchase.  They are supplied by many companies, stating that the magnets are ‘Rare Earth’.  However, as the magnet is only bonded (i.e. bonded together using a resin) it is not as strong or stable as being sintered.  ‘Ceramic’ Rare Earth Magnets, that have been produced using heat, are more stable and are what Bunting and other reputable magnetic separator suppliers use in their magnetic separators.  Bonded Magnets are ideal for many other applications;
  2. Physical damage. If a Magnetic Separator is dropped or hit, then this can result in the magnets inside breaking and this will affect the magnetic power.  Such damage often occurs when a Magnetic Separator is being cleaned.  Unknowingly, the Magnetic Separator is returned to the process line with the operator totally unaware that the magnetic separation capabilities have been seriously compromised.  Regular checks on the magnetic strength of the Magnetic Separators is recommended as part of an annual review and audit;
  3. Exposure to heat. When Rare Earth Magnets are exposed to heat over 80°C, there is a reduction in the magnetic strength.  When the temperature reduces, the magnetic field can recover.  However, if the temperature is very high then the magnetic strength will never recover back to the original state.  Typically Magnetic Separators are exposed to high temperatures if a process line is being cleaned using steam.  There are special Rare Earth Magnetic materials that are specially produced for high temperature applications, with Samarium-Cobalt being used in extreme circumstances;

Understanding the ability of a Magnetic Separator to hold its magnetic strength will help during the purchasing and maintenance processes.  Our Sales Team can provide help and assistance on:
