15 Magnetic Liquids Traps Keep Orange Juice Metal Free

Export Success to Fruit Juice Industry in Spain

In the past 18 months, Bunting has manufactured and supplied 15 Magnetic Liquid Traps to citrus juice producers in Spain.  The magnetic separators are used to capture and remove fine iron from the juice.

Need for Magnetic Separator Protection

Magnetic-Liquid-Trap-Cartridge-md-gasketsFine iron is commonly found in most food processes.  The origin of the metal contamination is often difficult to pinpoint.  Typical sources include:

  • When the fruit is harvested.  Dirt can often have a magnetic constituent and is carried on the surface of the fruit;
  • During transportation.  Even if the fruit is collected in plastic containers, metal contamination can be introduced from the transport (eg rust, metal dust, dirt).
  • When the fruit is processed.  The process of extracting the juice from the orange or grapefruit involves several stages where the fruit is sliced and compressed.  Wear to the process equipment will produce fine metal contamination.

Extracting the Metal Contamination

Due to the fine nature of the metal contamination, high strength magnets are required.  The Bunting Magnetic Liquid Traps are fitted with Neodymium Rare Earth Tube Magnets, the strongest permanent magnets presently available.

Fine iron contamination removed from fruit juice

The Magnetic Liquid Filters are designed to ensure maximum contact is made between the juice and the magnetic fields by forcing liquids through a tightly spaced grid of magnets.  Ferrous contamination is magnetically extracted from the liquid flow by the extremely powerful Rare Earth magnet design and held firmly on the surface of the Tube Magnets.

Cleaning of the Tube Magnets is simple.  On a designated frequency, determined by the level of contamination, the lid of the Magnetic Liquid Trap is removed.  The Tube Magnets are attached to the lid and are then manually wiped clean.

Dealing With Acidity

Fruit juices are naturally acidic, ranging between 2.00 and 4.80.  This level of acid has the ability to corrode standard welds.  In the Magnetic Liquid Trap, the Tube Magnets are welded onto the lid.  The welds are all to food grade standards.

20180424_161133
Welds eaten away by the acidic juice causing swelling and failure of the magnets

However, if standard welding materials are used, these will pit and corrode over time.  Eventually, the weld will be eaten away, allowing the ingress of liquid into the Tube Magnet casing.  This catastrophically damages the magnets, causing them to swell and lose their magnetic properties.  As the magnet swells, it can also split the outer casing.

Exporting Success

“We are now regularly supplying Liquid Magnetic Traps into Spain,” explained Dave Hills, Bunting’s Head of Sales.  “Our local representative has done a great job in helping the local citrus juice producers.  He understands the industry and fully understands the challenges.”

  • Flanges:  Bottom and top included, 6.35mm thick
  • Slide gate:  6.35mm thick
  • Viewing port:  Unit features a 9.5mm thick clear polycarbonate drawer front

Application

During the manufacturing process of any plastic or plastic product, it is possible for metal to be introduced into the process.  This could be from a wide variety of sources including the wear of processing machinery.

Bunting_Drawer_Filter_Magnets-0346

If metal contamination is not removed, it can damage processing equipment and result in increased final product rejects.  The Drawer Filter Magnets are used to attract, hold and thus remove any magnetically susceptible metal contamination.

Another Export Order

“This is another great export order for Bunting,”said Hills.  “Despite all the concerns about BREXIT, we continue to work hard supporting our regionally based distributors.  This is paying dividends as our sales overseas continue to rise.”

Practically Measuring Magnetic Separator Strength

Technically Assessing Magnetic Separator Power

A Magnetic Separator is designed to attract, capture and hold magnetic particles.  The magnetic strength needed to successfully achieve that design objective 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, the ‘gauss’ value can be very difficult to accurately measure.

20180424_173613
Fine iron contamination captured on Tube Magnets

There is a more practical method of assessing the magnetic strength.  This removes any ambiguity whilst providing simple, repeatable, and comparable data to assess most Magnetic Separators.

Measuring Magnetic Strength

The magnetic strength of a Magnetic Separator is often referenced in terms of ‘gauss’.  Gauss (symbolized G) is the centimetre-gram-second (cgs) unit of magnetic flux density. A flux density of 1 G represents one maxwell per centimetre squared (1 Mx ­ cm -2 ).  It is named after the German scientist Carl Friedrich Gauss.

Gauss can be measured using a Gaussmeter.  However, it is important to note that the Gauss rating on its own does not fully indicate the strength of a magnet.  Additionally, gaussmeters can give a range of readings dependent upon the orientation of the probe and several other variable parameters.

Proposals for Tube Magnets often include details of length, diameter and the gauss reading.  With the gauss reading being so difficult to test and prove, purchasers and users are unable to check that the Tube Magnets supplied actually meet the specification of the quote and the order.

However, in terms of Magnetic Separation the objective for the user is simple; the magnetic force must enable the attraction and capture of any magnetically susceptible metal.  That ability can be measured as a function of the effort needed to remove a specific steel item from the surface.

The Method

Measuring the effort needed to remove a steel item from the face or surface of a Magnetic Separator is achieved using a spring balance and is commonly called a ‘Pull Test’.  The magnetic test piece (e.g. a 6mm ball bearing welded onto a non-magnetic attachment ring) is clipped onto the end of the spring balance.

Bunting Magnetics Pull Test Kit
A Pull Test Kit ‘Spring Balance’

The magnetic test piece is placed on the surface of the Magnetic Separator and force applied at the other end of the spring balance until it is detached.  The force required to remove the magnetic test piece (measured in kgs) is recorded on the measurement scale of the spring balance.

Measurements are taken in the centre of the Tube Magnet and on the end poles.  They are repeated three times and the average recorded as the force required to remove the magnetic test piece at each point.

The following video explains the Pull Test technique.

This simple but effective method does not record or provide any indication of the gauss, but accurately provides data that can be used to compare the condition of a Magnetic Separator over time and compare the performance with other similar designs.

Pull Test Experiments

Magnetic Separator designs vary considerably depending on the application.  The Pull Test technique is suitable for measuring the magnetic strength of smaller Magnetic Separators such as Tube or Cartridge Magnets and Plate Magnets.

Tube or Cartridge Magnets are often used stand alone or as part of a Magnetic Separator configuration (e.g. Drawer Filter or Liquid Trap).

Bunting Magnetics Pull Test Kit
Magnetic Test Piece

A small steel ball is used as the magnetic test piece when measuring the magnetic strength of a Tube or Cartridge Magnet (the photograph shows a 6mm diameter ball)

The metal test piece is attached to the end of the Spring Balance and then placed into the magnetic field, being attracted to the magnetic pole.

Bunting Magnetics Pull Test Kit
Magnetically Attracted Metal Test Piece

In a series of experiments, we used the Pull Test technique to assess the magnetic strength of Tube Magnets with Ceramic (Ferrite), Standard Neodymium Rare Earth, and High Strength Neodymium Rare Earth Magnets.

The tests were undertaken using three different sizes of steel ball in the magnetic test piece (6mm, 12mm and 25mm) and introduced non-magnetic spacer to assess the magnetic strength at specific distances away from the surface (3mm and 6mm).  All the recorded measurements are in kilograms (kg)

3mm 1.5 2.5 4.6
6mm 1.1 1.5 2.25

Graph - High Strength Neo Tube Magnet

Note:  all measurements are recorded in kilogrammes.

In all cases, the drop off in magnetic strength as you move away from the surface of the Tube Magnet is significant and this highlights the need for metal contamination to come into contact with the surface.  Arrangements where the Tube Magnets are configured as a Grate (i.e. are lined up and equally spaced) commonly have a deflector above the gap between the Tubes that directs material in the area of maximum magnetic strength.

Comparison

The tests highlight the difference in magnetic strength on the surface, with high strength Rare Earth magnets producing nearly 3 times as much pull as Ceramic magnets.

Findings During Magnetic Separator Audits

Magnetic Separator Audits often highlight issues that had previously gone undetected.  The first check focuses on the physical integrity of the Magnetic Separator, inspecting welds, and assessing wear and damage.  Once these have been completed, the measurements are taken.

The most common findings when undertaking magnetic separator audits are:

Weld Failure

20180424_161133
Consequence of weld failure on a Liquid Magnetic Filter

Magnetic Liquid Filters, fitted into pipelines, have Tube Magnets that are welded to a lid and project down into the product flow.  Metal is attracted and captured on the surface of the Tube Magnet.

In cases where the welds have failed (e.g. poor manufacture, eaten away by acidic or alkaline liquids), liquid will seep into the tube and onto the magnets.  The magnets then swell and lose magnetic strength, ultimately splitting the outer stainless-steel casing.

Tube Magnet Wear

When material falls directly onto the surface of a Tube Magnet, over time the surface can be worn.  Wear usually occurs on the poles where magnetic particles have been captured.  Once the outer stainless-steel casing has been breached, the Tube Magnet should be replaced.

Weak Tube Magnets

Magnetic separation audits highlight the variance in magnetic strength of Tube Magnets.  Often, the Tube Magnets have been installed for some time and details of the original specification have been lost.  When testing the magnetic strength, some Tube Magnets are found to have very poor strength and provide little if no metal separation protection.  This is of great concern when the Tube Magnet is positioned to protect a particular item of processing plant where metal contamination damage could result in production downtime and costly repairs.

Conclusion

The Pull Test Experiments highlights the importance of physically checking the real magnetic strength of a Tube Magnet and not only replying on the stated gauss.  Including details of the force needed to detach a 6mm steel ball from the surface of the Tube Magnet in the request for quotation and the order, protects the user and ensures that the supplied equipment is as exactly as stated.

This ‘Pull Test’ measurement technique also enables a regular comparative test that will immediately highlight any drop in magnetic strength.  This can be used in annual audits or inspections as part of a plant’s quality management system.  A change in ‘pull’ strength may be the result of physical (e.g. failed weld, broken magnets from being dropped) or excessive heat.  The reduced magnetic force may result in the magnetic separator no longer being fit for purpose.

3 Successful Plastics Recycling Projects for Recycle Week

Celebrating Recycling Success

The theme of the 2018 Recycle Week (24-30 September)  is ‘Recycling. We do. Because it matters.’  Recycle Week is a celebration of recycling, organised by WRAP under the ‘Recycle Now‘ brand.

Recycling has never been more prominent in the news, with managing plastic waste high on the agenda.  We work with many plastic recycling companies and have provided many magnetic separators and metal detectors to remove metal contamination.  To celebrate Recycle Week we wanted to talk about plastics recycling success and also highlight the changes faced by companies recycling plastic.

EcoVyn Reduce Waste by 94% with Bunting Drawer Magnets

Bunting Magnetics Drawer Magnets at Ecovyn

EcoVyn Ltd is at the forefront of PVC compounding and brings pioneering new technology to the market place.  They offer one of the most advanced and innovative production processes in the UK producing reprocessed, blended and virgin compounds for a variety of applications.  By installing Drawer Magnet Filters, EcoVyn reduced their waste by 94%.

HFS Drawer Magnets Removes Metal from Recycled Plastics

HFS_Grate_Magnet_Plastics-1866

A French plastic recycling company installed the Drawer Magnets to remove fine iron contamination present in the recovered and granulated plastic.  If the metal is left in the reclaimed plastic, it causes serious defects in the new plastic product and can also damage processing equipment.

Metal Separation Module Cleans Recycled Plastics for Recapture Plastics

Bunting Metal Separation System Recapture Plastics LinkedIn

A new plastics recycling plant was built in Kent, UK.  The plant was designed to handle up to 25 tonnes per hour of reclaimed plastic.  Once shredded, the plastic is passed over a strong Drum Magnet (to remove small ferrous metals) followed by an Eddy Current Separator (to remove non-ferrous metals).  The end product is also passed through a Quicktron Metal Detector prior to the clean plastic being bagged ready for shipment.

Contamination Hinders Plastic Recycling

We work with many plastic recycling companies located across the world.  Every company is faced with the problem of contamination.  Contaminated plastic waste is worthless and processing is required to remove contaminants, such as metal and stone, to make this waste product reusable.

We are fortunate to be working with some amazing companies in the waste and recycling sector.  Their innovation and knowledge continually increases the amount of materials we can recycle and reuse.

A Rejuvenated RWM Exhibition

Busy Stand for Bunting Magnetics at RWM

At this year’s rejuvenated RWM Exhibition (NEC, Birmingham, 12th – 13th September), the Bunting Magnetics and Master Magnets stand proved to be a great success.  Being positioned in a prime stand in front of the entrance, and with working metal separators on the stand, visitors were drawn to see the latest developments in magnetic separation technology.

RWM 2018 Exhibition
Stainless Steel Magnetic Separator in action

In January 2018, Prysm Group announced that they had taken on the flagging RWM exhibition.  Attendance of the RWM exhibition in 2017 had been poor and many exhibitors had lost faith with the event.

At an event in the Google headquarters in London, RWM exhibition manager Nick Woore announced their intention to inject new life into the show.  The plans sounded positive, although there was still a great deal of doubt from many exhibitors.  In fact, in 2018 the number of exhibitors were lower than in 2017, but visitors numbers were higher.

“It was great to see people queuing outside the entrance on the first morning of the exhibition,” said Dave Hills, Bunting’s Head of Sales.  “As soon as the doors opened, our stand was full of visitors.”

Bunting had two operating production-sized metal separators on the stand:

Dave Hills also gave two presentations on ‘Stainless Steel Separation in Modern Day Recycling’.

RWM 2018 Exhibition

“Being able to show visitors the separation capabilities of the equipment was vitally important,” explained Hills.  “This made it easier to relate to their metal separation requirements.  Following the exhibition we will be conducting tests at our Master Magnets Redditch laboratory, where we can confirm the separation capabilities.  It is going to be a busy few months.”

Hills also explained the importance of a successful RWM.  “Recycling and good waste management is no longer an option but a necessity and it is essential that there is a UK based trade event.  We are looking forward to hearing how the organisers plan to further develop RWM for 2019.”

Metal Detectors Detecting More Than Treasure

Technology Keeping Waste Metal-Free

The BBC television series Detectorists has significantly increased the public’s awareness of metal detectors, but many people remain unaware of their importance in the recycling of waste materials.

399

Although the size and design of metal detector used in the recycling industry may be different to those used by the enthusiasts on the television show, the basic concept is the same.  When an electric current is passed through the coil of a metal detector, it creates a magnetic field.  If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own.  A separate control recognises that the new magnetic field has changed the metal detector’s magnetic field and identifies that there is metal present.

Metal Detectors are becoming increasingly important in the recycling industry.  Magnetic Separators and Eddy Current Separators are widely used to remove liberated ferrous, non-ferrous and even some stainless-steel metals, but are unable to separate metals that are imbedded in material or are unresponsive to these types of metal separators.

This is particularly important in recycling operations where the waste material is large in size and needs to be shredded or granulated.  A common location for the Metal Detector is on the conveyor prior to size reduction, where it identifies the presence of any metal that may damage the shredder or granulator.  The effect of metal damage can be costly in terms of repair and also downtime.  Typical waste materials include plastic, wood, and demolition waste.

There are primarily two different types of Metal Detector suitable for detecting metal in such conveyed material.  The Underbelt Conveyor Metal Detector is ideal when handling larger materials of variable shapes and sizes and the aim is to detect larger metal.  Two different coil designs mean that the Metal Detector is suitable for belt widths from 100mm to 1200mm.  This design of Metal Detector identifies and then stops the conveyor belt.  Operators then locate and manually remove the metal contamination.

The second type of Metal Detector surrounds the conveyor belt.  This increases the detection sensitivity and is also needed when there is a deeper burden depth on the conveyor.  There are various coil configurations, such as the QDC, QTA, and TN77, and the selection is based upon each application.

Once the waste has passed through the process of size reduction and separation, Metal Detectors are commonly used to check that metal is not present in the final product.  In some applications, the material will still be conveyed and so previously mentioned designs are used.  However, in applications where the particles are now significantly smaller different designs of Metal Detector are required.

Bunting Metal Separation System Recapture Plastics-0424In plastic recycling plants, Free Fall Metal Detectors such as the quickTRON 03R not only detect but also reject metal contamination.   Gravity free-fall style metal separators are specifically designed to isolate and separate any contaminated material moving in the product flow.  They automatically detect, pick up and reject both ferrous and non-ferrous from the product flow without any interruption to the line process.

As each application can be unique, selecting the optimum Metal Detector for an application is best achieved by conducting a site visit to understand the process and the objective.

Bunting Magnetics is one of the world’s leading suppliers of Magnetic Separators and Metal Detectors which includes the Master Magnets and Metal Detection branded range of equipment.

Metal Contaminated Sugar Alert

Latest Metal Contamination Food Safety Alert

On the 28th July 2018, the UK Food Standards Agency released a food alert announcing ‘Tereos UK recalls Granulated Sugar due to the presence of small metal pieces‘.  This is the third report of metal being found in food reaching the consumer in 2018 after six metal contamination alerts in 2017.

Metal In Sugar

Metal enters the food manufacturing process via many different avenues.  Metal can be present in ingredients being delivered to a food processing plant and unless removed at source can enter the process and cause significant damage.  Equipment failure and wear can also lead to metal contamination and is usually removed with the right combination of magnetic separators and metal detectors.

The source of the metal contamination in the granulated sugar is presently unknown and an investigation is most likely underway.  The sugar is sold in the UK by the retailers Iceland, Poundland, and Sainsbury’s and has been recalled.  The metal contamination will be costly in terms of direct financial cost and reputation.

Getting Metal Out of Sugar

Removing metal contamination from granulated sugar is commonly achieved using Drawer Filter Magnets and Plate Magnets.  Plate Magnets are installed in chutes where the sugar flows over the surface.  Due to the small size of the sugar granules Neodymium Rare Earth Plate Magnets are preferable, producing the highest magnetic attractive force to remove small ferrous and magnetically-susceptible work-hardened stainless steel.

SC FF drawer - no tr#14B20B

Due to the potential sticky nature of the sugar, sleeved Drawer Filter Magnets are often preferred, in an easy-clean design.  The Rare Earth Tube Magnet sits tightly inside a fixed stainless steel outer tube.  Cleaning forms part of a daily maintenance schedule, with the Tube Magnets being withdrawn from the sleeves to drag and deposit metal contamination in a discharge chute.

Magnetic Separation Audits

Bunting engineers conduct regular Magnetic Separation Audits at many food manufacturing plants.  An audit involves the visual and physical inspection of every magnetic separator in a plant to check on the location, suitability integrity (ie checking welds and for wear), and magnetic strength (which can deteriorate with excessive heat, weld damage, or if dropped).  In April three Magnetic Audits were conducted and highlighted a number of issues that have since been addressed.

RWM Becomes Metal Separation Test Centre

Interactive Stand 5Q11 at RWM

Visitor interaction is the theme of the Bunting stand at this year’s RWM (12-13 September, 2018, NEC, Birmingham, UK).  With their stand (5Q11) in prime-position opposite the entrance to the show, Bunting will invite visitors to take a lump of non-ferrous metal or stainless steel, place it on the belt of the metal separator, and witness separation.

Bunting Magnetics Europe at RWM16
The separation of stainless steel on a magnetic separator

“We wanted to do something different this year,” explained Dave Hills, Bunting’s Head of Sales.  “Visitor interaction is so important and we want people to handle the metal and then see what happens when they place it on the belt of the metal separation system.”

Operating on the stand at RWM will be a production-sized Eddy Current Separator and Stainless Steel Magnetic Separator, and demonstration-sized model of the popular Permanent Overband Magnet.

On the Stainless Steel Magnetic Separator, visitors will be able to separate several different materials.  These include large lumps of fragmented stainless steel, from secondary metal recycling plants, and printed circuit boards (PCBs) from electronic recycling operations.

The Stainless Steel Magnetic Separator uses a patented high strength magnetic roll that generates enough attractive power to separate even the weakest magnetic materials.  When passing through a shredder, the edges of stainless steel become weakly magnetic and this enables the effective separation.  Also, PCBs have small components that are weakly magnetic and these are attracted by the strong magnetic field and separated from non-magnetic materials.

Dave Hills will be speaking about the Stainless Steel Magnetic Separator in the Alternative Fuels Theatre on Wednesday 12th (12:30-13:00) and Thursday 13th (11:45-12:15).

Eddy Current Separators are a common feature at the RWM exhibition.  The Master Magnets design focuses on maximising non-ferrous metal separation whilst maintaining product purity levels.  The ability to produce the optimum separation of non-ferrous metals is dictated by the design of the high speed rotating magnetic rotor and visitors will be able to place non-ferrous metals on the separator and witness the dramatic and violent separation.

Bunting Master Magnets at RWM17
Non ferrous metals being separated on the Eddy Current Separator

As the Permanent Overband Magnet is one of the most commonly used magnetic separators in the recycling and waste industry, it was important to have a model on show.  Hundreds of Permanent Overband Magnets are built at the Redditch manufacturing facility each year and they can be seen on many pre-sorted refuse operations recovering steel cans and mobile plant such as crushers and screens.

“Participating in a demonstration is different to simply watching,” explained Hills.  “Visitors to the stand can choose the item they want to separate and then see what happens on the metal separator.”

Metal Recovery Focus at CARS 18

Metal Recovery Equipment on Show at CARS Exhibition

At the CARS 2018 exhibition (11-12 July 2018, NAEC, Stoneleigh, UK), the focus on stand M6 will be on maximising the recovery of metal whilst also maintaining purity levels.

The Complete Auto Recycling Show (CARS) is Europe’s premier event for auto recyclers and material processors. It is the only event of its kind, drawing over 1,200 attendees from across the globe in 2016.

Unlike traditional trade shows, visitors get the chance to experience not only the indoor exhibitions, but to see working line demonstrations, participate in offsite tours, visit the Skills Lab and access the Conference Theatre – all included within the free ticket.

Master Magnets, the recycling focused division of Bunting Magnetics Europe Ltd, will be demonstrating the separation and recovery of non-ferrous metals and stainless steel on stand M6.

“Our focus is on recovering as much metal as possible in a high value grade,” explained Dave Hills, Bunting and Master Magnets Head of Sales.  “There is always a balance between recovery and purity and the best results often come from several stages of separation.”

Master Magnets has a complete range of metal separation equipment for every stage of metal recovery.

Ferrous Metal Separation

drum_magnet_installation

The primary metal separation stage in any recycling plant focused on ferrous metals.  Large Drum Magnets, specifically designed for the arduous environment, are commonly used along with smaller Drum Magnets and Pulley Magnets.

Non Ferrous Metal Recovery

Eddy Current

Eddy Current Separator designs have been perfected to enable the recovery of even the smallest non-ferrous metals.  Two rotor configurations (ie concentric or eccentric) are available to suit the specific application.  Recent developments include a precise splitter positioning system to maximise recovery and purity.

Stainless Steel Separation

Gershow-System_4336-300x225

Stainless Steel Magnetic Separators are a relatively new addition to the metal separation range of equipment that has been extremely popular in USA secondary metal processing plants.  There are two variations available:

HISC (High Intensity Separation Conveyor) – This enables the magnetic separation of small and mid-sized stainless steel – 10mm to 40mm (½” to 1½”) – and for wire-cleaning applications.

SSSC (Stainless Steel Separation Conveyor) – With a patent magnetic circuit design of high-intensity neodymium magnets, the SSSC can remove up to 94% of irregular shaped stainless steel – up to 125mm (5”) in size – from auto shredding or wire chopping stream.

On stand M6 at the CARS exhibition there will be demonstrations of both non-ferrous metal recovery on an Eddy Current Separator and Stainless Steel separation.
