3 Magnet Audits Conducted For Food Safety

Testing Magnetic Separators in Food Processing Plants

In one week, we have conducted Magnetic Separation Audits at three separate UK food processing plants.  The audits form part of the quality management system of each company and are used for both internal and external food quality and safety assessments.

A Magnetic Separation Audit involves the physical testing and inspection of all Magnetic Separators.

Physically Testing the Magnetic Strength

The first part of the inspection assesses the magnetic strength.  This involves using a Pull Test Kit which includes a spring balance and various sizes and shapes of magnetically susceptible steel test pieces.  A Gauss Meter is not used as the readings can be inaccurate and variable.  The physical test involves placing the steel test piece on the surface of the magnet (on a magnetic pole) and measuring the amount of force (in kgs) that is needed to remove the item from the surface of the magnet.  This is then repeated and an average reading recorded.

Visually Assessing the Magnet

The second set of tests involve the visual inspection of the Magnetic Separators and we are checking for:

  • The amount of metal contamination captured by the Magnet;
  • Signs of damage or wear;
  • Weld integrity;
  • Fixings and any related safety issues (e.g. missing restraining nuts);
  • Cleaning regimes and ease of cleaning;

Findings

In the three recent audits there were a number of findings including:

  • Magnetic Separators were in locations where it was extremely difficult to clean and may be considered a safety risk;
  • Welds on a Magnetic Separator had been eaten away by the acidic product resulting in liquid penetrating the Tube Magnet.  This caused the magnets to expand within the stainless steel casing and also destroyed the magnetic field;
  • Damaged Tube Magnets
    Tube Magnets where the welds have failed and liquid has seeped inside the stainless steel casing causing the magnets to expand and lose all magnetic strength
  • The magnetic strength of some Magnetic Separators (especially those that had been installed for some time) was very poor and the level of separation would be minimal;
  • In some locations, Magnetic Separators had been removed from the process but were still registered in the system;
  • The positioning of some Magnetic Separators could be changed to improve the metal separation performance;

Action

Following the Magnetic Separation Audit, a full report, with all the test results, is written and submitted with recommendations.  This then forms part of the food processing company’s internal quality audit system and is refereed to when there are inspections from external third parties and customers.  Commonly the audit is repeated on a annual basis using the same test parameters.

Similar audits are also undertaken in other industries including Plastics Production and Recycling.  An annual health check ensures that the Magnetic Separators are performing to their maximum potential and achieving the separation goals for which they were originally installed.

Polymer Training and Innovation Centre Protected by Bunting Drawer Filter Magnet

Magnetic Separator Technology for Plastics Training

The Polymer Training & Innovation Centre in Telford has added a Bunting Magnetics Drawer Filter Magnet to the range of equipment at their plastics manufacturing training facility.  The FF Drawer Filter Magnet attracts and captures any fine and coarse magnetically susceptible materials that enter the plastics manufacturing process.

Bunting FF Grate Magnet
A Bunting Magnetics Europe FF Grate Magnet included in a plastics production line at the Polymer Training and Innovation Centre in Telford

The Polymer Training & Innovation Centre provides polymer training and consultancy, specialising in injection moulding, blow moulding and extrusion training.  They are a technical training and consultancy business that is owned by City of Wolverhampton College.

At their Telford training facility, the Polymer Training & Innovation Centre has working production-sized plastics manufacturing equipment for injection moulding, blow moulding, thermoforming, materials handling, and a wide range of other important ancillary equipment.

Technical Trainer, Andrew Dermody, explained the importance of trainees having practical training on the equipment.

“We have great support from the industry and equipment manufacturers such as Bunting.  This support means that we can deliver practical training, with a hands-on approach, and that is the best way for our delegates to learn.  Having the Drawer Filter Magnet installed exactly as it would be in a production plant, is an ideal way to show our students best-practice and highlight the importance of metal removal.”

Bunting FF Grate Magnet

The training facility at Telford was refurbished in early 2017 and Bunting supplied the FF Drawer Filter Magnet in March 2018.  The FF Grate Magnet is bolted onto the bottom flange of a Summit Systems fed hopper.  The Magnetic Separator has a transparent front plate so that operators are able to see the material passing through or held within the system.  Virgin plastic beads fall from the hopper through two rows of high strength Tube Magnets, which attract and hold any magnetically susceptible materials.  The Tube Magnets use ultra-strong, permanent, Neodymium Rare Earth Magnets.  The cleaned plastic beads are then fed into the Engel injection moulding machine.  Removing all metal contamination ensures that the final plastic product is free from defects and reduces the amount of waste and potential damage to moulding machines.

Bunting FF Grate Magnet

On a regular frequency, dictated by the amount of metal captured, the Tube Magnets are removed as one complete assembly from the housing and cleaned.  The design of the Drawer Filter Magnet means that removal of the Magnet Assembly is quick and easy, keeping maintenance times to a minimum.

“The Bunting design is good as it is very visible,” said Dermody.  “Often Magnetic Separators are placed out of sight in hoppers, which means that they can be forgotten.  In this installation, the Drawer Filter Magnet is right in front of the machine operator and the clear front allows easy visual checking of the magnets.”

Bunting also supplied Drawer Filter Magnets for use in the classroom and the Polymer Training & Innovation Centre plan to incorporate ‘metal separation’ as one of the course topics.

The Drawer Grate Magnet is widely regarded as standard for the plastics industry and Bunting has supplied thousands to plastics manufacturing operations globally.

“It is great that delegates are able to see, in practice, the importance of having good Magnetic Separation equipment in the plastics process,” said Tom Higginbottom, Bunting’s Sales Engineer.  “Even with virgin raw materials, there is always a small amount of fine ferrous metal contamination and there is always the risk of larger tramp iron that could seriously damage the injection moulding machine.”

On the 18th April 2018, the Polymer Training & Innovation Centre is staging the Technivation event at their recently upgraded training facility in Telford.  During the day there will be a series of short technical presentations, the opportunity to experience their Polymer on-line simulation software, and the chance to meet and talk with primary and secondary equipment suppliers including Bunting Magnetics.  Visitors will be able to learn more about Polymer Apprenticeship’s and Funding and discuss their organisations own training requirements.

Changes in E Waste Management Highlighted at IERC 2018

Future of Electronics Recycling Discussed at 17th International Electronics Recycling Congress

IERC 2018 closed on Friday 19th January 2018 with a stark warning that changes are needed in the global management of E-waste.  Attending the congress were 480 international experts from 42 countries.

WEEE E WasteBunting Magnetics Europe’s Managing Director, Simon Ayling, was at the congress for the first time.

“All the leading companies and organisations involved in E-waste were present at the congress,” said Simon.  “There was a very honest and open assessment of the present state of the industry, with a focus on what needs to change.”

Many visitors to the Bunting Magnetics stand had issues with separating Stainless Steel.

“Stainless steel is clearly a major issue when processing WEEE.  Up until now, it has been difficult to effectively [physically and economically] extract the stainless steel.  This then causes problems with shredder wear and the contamination of the end product.  With the HISC and SSSC, we have Magnetic Separation solutions for both small and large sized Stainless Steel.”

At IERC 2018, there was a focus on change.  As developing countries introduce tighter restrictions on the shipment of waste in general [EPPM – China raises drawbridge on incoming overseas plastic waste], a more holistic approach is needed.

New technology, like the Bunting Stainless Steel Magnetic Separator, and increased automation were identified as being vital to improve WEEE recycling rates.

Bunting Master Magnets at RWM17

The amount of E-waste is ever-increasing and the shrinking product size is making recycling increasingly difficult.  Rising collection costs and falling value of the end recycled product may lead to more localised e-recycling.  There also needs to be a clear political strategy with a standardisation of regulations.

WEEE E Waste“It was clear that the industry faces a challenging future,” observed Simon.  “Being able to successfully recycle WEEE can be prohibitively expensive and is further complicated with local and global environmental regulations.  Companies involved in processing E-waste are having to continually modify their businesses to survive in an ever-changing industry.  Hopefully, our Magnetic Separation technology will help.”

The Challenges of Removing Fine Iron from Powders

Magnetic Separators Designed for Processing Powders

Removing metal contamination when the tramp metal and material is granular is far more straightforward than when in a powder form.  To determine the best solution to remove fine iron contamination from powders, it is necessary to have a good understanding of the way the fine materials behave.

Powders are produced and used in a wide variety of industries including food, pharmaceuticals, refractories, and chemicals.  It is estimated that 80% of materials used in industry are in a powdered form.

flour-791840_960_720A ‘powder’ is defined as fine dry particles produced by the grinding, crushing, or disintegration of a solid substance.  The nature of a powder means that the handling and processing tends to be problematic as powders exhibit similar properties to both solids and liquids.

Metal contamination, commonly in an iron form, can be introduced into a material at any stage within a process.  Tramp metal that is undetected and remains in the product before the powder production stage, becomes significantly reduced in size and, subsequently, increasingly difficult to extract.

Magnetically susceptible metal contamination (i.e. iron) is commonly removed using Magnetic Separation Equipment, which traps metal using Ceramic Ferrite or Rare Earth Neodymium Iron Boron (Neodymium) Magnets.  Although there are Magnetic Separators where the magnetic field is produced via an electrical current, the vast majority utilize permanent magnets such as Ceramic Ferrite and Rare Earth Neodymium Iron Boron (Neodymium).  Ceramic Ferrite Magnets produce low strength but deep magnetic fields, while Neodymium Magnets create the strongest permanent magnetic presently commercially available.

Where Does The Metal Originate?

Metal contamination commonly originates in a powder from two sources:

  1. Primary large tramp metal, such as a nail, screw or bolt;Tube Cartridge Magnets Bunting Magnetics-5
  2. Primary or Secondary fine tramp iron. Primary fine iron or magnetic particles are often present in the raw material.  This originates from primary processing, transportation, or even naturally occurs in the original material.  Secondary fine iron originates from a larger tramp metal source that has been reduced in size during the process.  Typically, this could be from a nail, screw or bolt that has been through a size reduction process, or from damaged or worn processing equipment.  Another common source of secondary fine iron contamination is rust, falling into the process from weathered and worn processing equipment such as chains, hoists, and building cladding.

The separation and detection of tramp metal is easier when the metal contamination is in a larger form and can be successfully removed using a wide range of suitable Magnetic Separators and Metal Detectors.  Magnetic Separators using standard strength Ceramic magnets, with deep magnetic fields, are ideal.  A good example is the Plate Magnet, often installed in a chute, in a housing, or as part of an In-Line Magnetic Separator.

Quicktron05A_Sodium Bicarbonate 2

Larger metal contamination is also easier to detect on a Metal Detector.  Metal is detected as it passes through the coil of the Metal Detector and an automatic reject system removes it from the flow.  For detection, the magnetic field generated by the Metal Detector has to see a state change.  Finer sized metal produces a lesser state change and thus increases the difficulty in detection.

In a project in Pakistan, a processor of fine Sodium Bicarbonate is using a Quicktron Metal Detector to remove the larger tramp metal.

Removing larger tramp metal with a Magnetic Separator and Metal Detector prior to the processing stage not only prevents the metal from being reduced in size (e.g. converted into a secondary source of fine iron contamination), but also protects delicate processing equipment such as granulators, shredders, and mills from being damaged by the metal.

Once in a powder form, there are processing parameters to consider when assessing the optimum method to remove fine iron contamination.

How Does a Powder Flow?

When a powder is sprinkled, it remains light and free.  However, when the same powder is vibrated or compressed, it may become very dense and even lose the ability to flow.

Individual grains in a powder cling to each other in clumps, in accordance with the Van der Waals force.  This coagulation often results in the fine iron being trapped in among clean product.  The ability of any Magnetic Separator to attract, hold and separate the fine iron is dependent on the iron being as close to the magnetic field as is physically possible.  If the fine iron contacts the surface of a Magnetic Separator with a high strength magnetic field, it will be held.  However, when the fine iron is held inside a coagulation of powder, then it could be held out of the reach of the maximum magnetic force.  Thus, it will not be separated.

The way a powder flows impacts on the design of the Magnetic Separator.  Powders flowing in a hopper may experience classic flow problems such as ratholing, bridging or flooding, all of which could be exacerbated by the design of Magnetic Separator.

Different Designs of Magnetic Separator

Plate Magnets Bunting Magnetics-9797High strength magnetic fields, as produced by Neodymium, are needed to capture fine iron metal contamination.  There are four main magnet configurations suitable for handling powders.

  1. Tube Magnets (also known as Rod Magnets and Cartridge Magnets), often in a multi-rod Grate configuration;
  2. Flat-faced Magnetic Plates;
  3. Cone-shaped Magnets;
  4. Magnetic Drums with a curved magnetic arc;

Although occasionally a Tube Magnet may be used on its own, it is more commonly part of a larger multi-cartridge Grate system.  The Magnetic Grate is designed to fit inside a hopper, or can be supplied complete with a housing (i.e. as a Drawer Filter Magnet).ff-neo-4

In operation, powder falls freely onto the surface of the Tube Magnet where fine iron strikes the surface and is held by the strong magnetic field.  To ensure that the powder makes contact with the Cartridge surface, deflectors are often deployed above the gaps between the Cartridges.

Powder build-up on the surface of a Magnetic Cartridge will reduce the separation efficiency.  Also, in severe cases, a slight build up on the surface of the Cartridge may quickly cause a blockage of the whole housing.

Such blockages can be prevented by ensuring that there is optimum space between the Magnetic Cartridges.  Also, in some cases, the mounting of an external vibrating motor on the side of the hopper or housing will provide enough disturbance to prevent any material coagulation.  The frequency of the vibration needs careful consideration as it could affect the flow ability of the powder.  Additionally, when vibrators are used, the Magnetic Cartridges need to be manufactured to withstand prolonged periods of vibration.

Bunting Teardrop Tube Magnet

‘Teardrop’ shaped Tube Magnets are specifically designed to stop the build-up of fine powder on the surface.  The sharp edge of the teardrop faces up into the product flow and allows material to flow around the edge and into the magnetic field.  Magnetic particles are captured and held underneath the Tube Magnet.

Flat-faced Magnetic Plates are ideal when it is possible for the material to flow over the surface.  For fine iron removal, the Magnetic Plates would use high strength Neodymium Magnets.  This magnetic field is further enhanced when a Tapered Step is added to the face of the magnet.  Captured iron migrates behind the step and away from the material flow, reducing the risk of re-entering the cleansed product.

As well as being fitted into chutes, Magnetic Plates are incorporated into housings.  The Plate Housing Magnets resist bridging and choking to remove tramp iron and ferrous fines from flow-resistant bulk materials.  The stainless steel housings mount easily to enclosed spouting or directly on processing equipment.

There are optional square, rectangular, and round adapters for easy connection to existing chute work.  A baffle at the top of the housing helps break up clumps and directs product flow over the unit’s two powerful Plate Magnets.

Bunting Magnetics In Line Magnet

Plate Magnets are also used in In-Line Magnets and there are two designs:

  1. Gravity In-Line Magnets (GIM) – The Plate Magnets are positioned in round, sloping spouting where material is under gravity flow.  For effective tramp metal capture, the spouting should be angled no more than 60° from horizontal;
  2. Pneumatic In-Line Magnets (PIM) – These designs are for use in dilute phase pneumatic conveying systems (up to 15psi). They can be installed easily with optional factory-supplied compression couplings and work best in horizontal runs with the plate magnet down to take advantage of material stratification;

Another design of In-Line Magnet is the Center-Flow, although the magnetic field is generated in a Cone configuration instead of a Plate.  The Magnetic Cone is positioned in the center of the housing, allowing the powder to flow in the space left between the housing.  Center-Flow In-Line Magnetic Separators are commonly used in dilute-phase pneumatic conveying lines up to 15psi.

To achieve optimum contact with the product flow, a conical magnet is suspended in the center-line of the housing.  This tapered, exposed-pole cartridge has a stainless steel “nose cone” to direct the flow of materials around the magnet.  The tapered poles of the cone magnet allow ferrous fines to collect out of the direct air stream.  Additionally, the trailing end of the magnet is an active magnetic pole and holds any tramp metal that is swept down the cone.

Both types of In-Line Magnet are designed with clamps and doors to enable easy access for cleaning.

drumIn specific applications, a high strength Neodymium Drum Magnet will enable the best level of separation.  The Drum Magnet is gravity-fed, usually via a Vibratory Feeder.  The Drum Magnet has a stationary high-strength magnetic arc positioned inside a rotating outer shell.  When material flows onto the drum magnet, the magnetic field projected by the stationary magnetic assembly inside the shell captures fine iron and holds it securely to the drum’s stainless steel surface.  With contaminants removed, the good product falls freely to a discharge point.  As the drum rotates, the captured fine iron travels along the drum surface and out of the magnetic field, where it is discharged.

There are various magnetic field configurations possible, but the most suitable for removing iron from powder is one that produces a Radial Magnetic Field.  This ensures that once captured, the fine iron does not leave the Drum surface until it moves out of the magnetic field.

Processing powder on a Drum Magnet presents more difficulties that other designs of Magnetic Separators.  Firstly, it is recommended that the Vibratory Feeder has an air bed to produce a consistent feed of powder.  Standard Vibratory Feeders may deliver powder in clumps, significantly affecting the separation performance.

Secondly, the shell of the Drum Magnet should be rotated at high speeds.  This will result in some of the powder pluming, and this can be minimized by keeping the distance between the end of the Vibratory Feeder Tray and the rotating surface of the Drum Magnet to a minimum.

The high rotation speed of the Drum Magnet significantly reduces the amount of product lost to the magnetics.  This is because there is less material on the surface of the Drum at any one time, reducing the chance of entrapment.

The use of Drum Magnets operating at high rotational speeds has been very successful in removing fine iron from abrasives, refractories, and other applications where the material has a high specific gravity.

Ensuring Powder is Metal-Free

As the demand for finer and purer powders increases, so does the need to remove even the finest iron.  Understanding the properties and behavior of the powder is vitally important when considering the optimum method of fine iron separation.  Often the ultimate solution is a series of Magnetic Separators and Metal Detectors located at strategic points within the process.

Environmental Issues Highlighted at Interplas 2017

Interplas Exhibition Well Supported by Plastics Industry 

On the morning of day 2 of the Interplas 2017 exhibition (26th – 28th September, NEC, Birmingham, UK), BBC Radio 5 Live featured a news item reporting that UK pub operator, JD Weatherspoon, had decided to stop using plastic straws.  This announcement highlighted the challenges facing the plastics sector.

Bunting Magnetics Europe at Interplas 2017

Interplas 2017 is the UK’s premier show for the plastics sector and proved to be a great success.  As experienced at many UK trade exhibitions, the footfall was not as seen at shows in the USA, Germany or other European countries, but the visitors to the Bunting stand had specific metal contamination issues in their plastics production process that needed a solution.

However, plastics and their environmental impact continue to hit the headlines.  Indeed, there were two large posters on the stand of the British Plastics Federation asking:

“As we supply equipment both to companies manufacturing primary plastic products and recycling plastics, we see the problem from both sides,” said Dave Hills, Bunting’s Head of Sales.Bunting Magnetics Europe at Interplas 2017

“Even when manufacturing primary plastics, it has been common and good practice for companies to recycle and reuse their plastic waste for many years.  Indeed, this often necessitates the need for Magnetic Separators and Metal Detectors, removing any rogue metal introduced during this recycling process.”

“However, the real challenge is collecting, processing and then producing a usable plastic product from recovered secondary plastic materials.  Again, we have installed Metal Separation Systems to remove ferrous and non-ferrous metals (eg at Recapture Plastics), but there remain challenges with the end market for the final recycling-sourced plastic product.”

There appears to be a growing appetite for focusing on the issue of plastics in the environment.  The implementation of charges for plastic bags by firstly the Welsh, and then the UK governments may be the first of many initiatives to reduce the use of plastic products.  The latest announcement by JD Weatherspoon about banning plastic straws is expected to be followed by similar announcements by other major coffee shops and food outlets.

At Interplas 2017, the vast majority of the exhibitors were focused on primary plastic production.  With the ever-increasing global focus on environmental issues, we wonder how different the exhibitor and visitor make-up will be at Interplas 2020.

Getting Metal Out of Plastic on the Bunting Stand at Interplas 2017

Bunting Magnetics Magnetic Separators and Metal Detectors at UK Plastics Show

The latest Magnetic Separation and Metal Detection technology will be on display on the Bunting Magnetics Europe stand (Hall 4, Stand H11) at Interplas 2017 (NEC, Birmingham, UK, 26th – 28th September 2017).

Bunting FFS Magnet-0064A
Bunting FF Drawer Grate Magnet

Bunting Magnetics is one of the world’s leading suppliers of Magnetic Separators and Metal Detectors.  The European manufacturing headquarters are based in Berkhamsted in Hertfordshire, UK and they have an extensive overseas network of distributors and marketing agents.  In January 2017, the company acquired Master Magnets, significantly expanding their range of Magnetic Separators and Metal Detectors.

“Interplas is the number one exhibition for the plastics sector in the UK,” said Dave Hills, Bunting’s Head of Sales, “and the show gives us a great opportunity to meet many existing and potentially new customers.”

Bunting Magnetics has a strong global relationship with the plastics sector.  Many of their Magnetic Separators have been designed specifically for use in the manufacture and recycling of plastics and plastic products.

The Magnetic Separators and Metal Detectors on the Bunting stand at Interplas are designed to capture, identify and remove metal contamination.  The presence of rogue metal damages processing equipment and affects the end-product quality and reject rates.

Bunting BPI-6151

The FF Drawer Grate Magnet is specifically designed for removing magnetically-susceptible particles from plastic.  The standard model has 2 banks of Neodymium Rare Earth Tube Magnets mounted inside a sealed housing.  Other variations are available including a low profile design for positioning underneath large hoppers and silos. Magnetic Separators with Neodymium Rare Earth Magnets remove even the smallest magnetically-susceptible particles.  On the stand will be examples of extremely strong Magnetic Grates, Plate Magnets, Tube Magnets, and the industry-standard FF Drawer Grate Magnet.  Visitors will be invited to test the magnetic strength for themselves.

Bunting Magnetics Europe at RWM16“This combination [FF Drawer Grate Magnet and the quickTRON Metal Detector] offers the best method of removing metal from free-falling materials,” explained Dave Hills.  “The Magnetic Separator captures and holds any magnetically attracted metals such as steel screws, bolts, steel slithers from worn equipment, and even work-hardened stainless steel.  This always proves to be the bulk of the metal contamination.For a complete metal separation solution, the FF Drawer Grate Magnet is fitted above a quickTRON Metal Detector.  The Metal Detector then identifies and rejects any non-ferrous metals.

“Any remaining metal will be identified as it passes through the Metal Detector and then ejected.  The cleansed plastic can then proceed safety into the next stage of the process, whether than is to the extruder or granulator.”

A working, production-sized model of the combined FF Drawer Grate Magnet and quickTRON Metal Detector will be on the Bunting stand at Interplas.  Regular demonstrations will enable visitors to witness the capabilities of the complete metal separation system.

A range of pTRON Metal Detectors designed for use in Pneumatic transportation lines will also be on display on the Bunting stand.

With the acquisition of Master Magnets, Bunting also has an extensive range of Magnetic Separators and Eddy Current Separators for the recycling sector.

“The combined experience of Bunting and Master Magnets means that we have a solution for most metal separation problems.  The Master Magnets Eddy Current Separator is an industry standard and is used to remove non-ferrous metals from plastics in recycling operations across the world,” said Dave Hills.

Combined Magnetic Separation Force at RWM2017

Bunting Magnets and Master Magnets Exhibit at Major Recycling and Waste Exhibition

For the first time, the combined Magnetic Separation force of Bunting Magnetics Europe Ltd and Master Magnets will be on stand 5P80 at RWM 2017 (NEC, Birmingham, UK 12th – 14th September 2017).

Bunting Magnetics acquired Master Magnets in January 2017 and the two companies have annually exhibited separately at RWM, the UK’s leading waste and recycling show.  The joint stand will be the first time that the companies have combined forces at a major international exhibition since the acquisition.

Both Bunting and Master Magnets have a rich and long-standing history of supplying separation equipment to the recycling sector and the acquisition creates a world-leading manufacturer of Magnetic Separators, Eddy Current Separators, and Metal Detectors.

“RWM 2017 provides us [Bunting and Master Magnets] with the ideal platform to demonstrate to our customers the benefits of the new partnership,” said Dave Hills, Bunting’s Head of Sales.

A working production-sized Eddy Current Separator and High Intensity Separation Conveyor (HISC) will be on the stand at RWM.  In 2017, Master Magnets has had a record year for the sale of Eddy Current Separators, with shipments around the world.  On the stand, the Eddy Current Separator will be shown separating small non-ferrous metal particles from non-metallic materials.

Bunting’s HISC has provided recycling companies with a much-needed solution for separating stainless steel.  Since the original conception, Bunting has developed variants and recently released the SSSC to recover stainless steel of a size up to 13cm (5”).Bunting Magnetics Europe at RWM16

“Our stand will be interactive and dynamic,” said Dave Hills.  “We want visitors to witness metal separation first hand.  Ideally, we want people to bring samples.”

The Bunting Magnetics and Master Magnets stand is focused on recovering and separating metals.  In the recycling sector, this includes separating beverage cans from household refuse using an Overband Magnet; stainless steel from shredded computer hard-drives with the HISC, and small non-ferrous metals in an automobile shredding operation with an Eddy Current Separator.

MasterMagnets_ECS-0634

“Recovering or removing metal is a vital stage in the recycling process.  Our Metal Separators are used to recover metal for on-sale as with UBCs, and to remove problematic metal as found in materials such as reclaimed plastic.  Fortunately, our team has a great deal of knowledge and experience and we work closely with companies to maximise the separation or recovery of the metal.”

A mobile Metal Separation Module incorporating a high-intensity Magnetic Drum (for ferrous metal separation) followed by an Eddy Current Separator (for non-ferrous metal separation) has recently been launched by Master Magnets and technical information will be available on the stand.

Also promoted at RWM 2017 will be the popular range of Master Magnets Overband Magnets.  The designs include both permanent and electromagnetic configurations.  The permanent Overband Magnet is commonly used in Materials Recovery Facilities across the UK and Europe to recover steel from pre-segregated waste.  Larger and more powerful electromagnetic Overbands are used for more arduous environments and applications.

“With Bunting combining forces with Master Magnets, we now have a range of Magnetic Separators and Metal Detectors to suit all applications.  We are looking forward to meeting and helping visitors solve their metal separation problems at RWM,” said Dave Hills.

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 written by Geyer, Jambeck and Kara Lavender Law is concerning with a prediction of 12 million metric tonnes of plastic being in landfill or the natural environment by 2050.

The application of plastics technology continues to grow, with the UK launching a new plastic £10 note in September 2017.  And this is because plastics technology produces such versatile and resilient products, properties that make it equally difficult to manage once it has been used and becomes waste.

Designing plastic products to enable easy reuse and recycling appears to be the key.  However, often the aesthetic appearance of a plastic packaging product takes precedence over the post-use waste functionality.

As an equipment supplier, we understand the difficulties of recycling plastics.  Even though we can remove the metal contamination with Magnetic Separators, Eddy Current Separators, and Metal Detectors, a substantial amount of further processing is required with colour and plastic type separation is often required.  We will be exhibiting at Interplas 2017 (NEC, Birmingam, UK 26th – 28th September), the UK’s premier show for the plastics sector, and it will be interesting to see and hear the ideas and thoughts of the industry.

Designers of plastic products, especially packaging, need to be creative and give reuse and recycling a higher priority during the concept phase.  With the prediction of an ever-increasing production of plastic, a workable environmental strategy has never been more important.
