Ferrous Metal Prices Fall

In a clear illustration of the volatility of the metals markets, the price of Ferrous Metal has dropped by £20 to £30 per tonne in the past few weeks as reported by MRW.  Further drops are also expected.

There is now a question whether the faint signs of recovery for other metals such as Stainless Steel and Nickel will be short-lived.

At the Waste 16 exhibition in Salford, UK, scrap and waste processors were explaining the difficulties of planning future investment in the present economic climate.  In terms of Magnetic Separation, that meant investing in equipment to enable better and cleaner metal recoveries, or the separation of materials previously deemed difficult (eg Stainless Steel or even Printed Circuit Boards).

When metal prices were high, the separation objective was simply focused on getting as much metal out as possible without necessarily assessing metal recovery rates or purity levels.  When assessing metal separation and recovery applications, we ask about metal recoveries and purity levels, and it is not unusual for this information to be unavailable or unknown.

With metal prices so volatile, and not in a positive way, the importance of maximising separation and purity increases.  A small gain in both can generate more income whilst processing the same tonnage of material.

It is an issue we discussed with many visitors at Waste 16 and will probably remain a hot topic when we exhibit at RWM in September 2016.

High Interest in Magnetic Separation at Waste 16

Whilst exhibiting at the Waste 16 exhibition in Salford, UK, last week (9th June AJ Bell Stadium), we had the opportunity to talk with companies about ways to improve metal separation and recovery.

The Waste 16 exhibition had both internal and external areas and featured a wide range of recycling technology from mobile screens and crushers to magnetic separators.  Organised by Skip Hire Magazine, this was the 3rd year of the show providing companies based in the North with their own waste and recycling exhibition platform.

We had attended in 2015 and, in 2016, Bunting Europe was back as one of the headline sponsors.

Maximising metal separation was a major concern for many of the companies visiting the Bunting stand.  The volatility of metal prices and the need for increased purity of recycled materials led to questions about enhancing existing Magnetic Separator systems.

Visitors also wanted discuss the separation of Stainless Steel and Printed Circuit Boards as achieved using the HISC.  This ultra high strength Magnetic Separator enables separation of materials not previously possible.

As well as more advanced Magnetic Separators, a range of standard Magnetic Separators including FF Drawer Magnets, Plate Magnets and In-Line Magnets were on display.  This gave visitors the opportunity to test the magnetic strength trying to pull bolts off the surface out of the strong magnetic field.

Waste 16 again proved to be a good exhibition and we were really pleased with the high level of quality leads.

Bunting Metal Separation Module Cleans Recycled Plastic for Recapture Plastics

Bunting Magnetics Europe Ltd has manufactured and supplied a complete Metal Separation Module and Metal Separator to Recapture Plastics to cleanse recycled plastic of metal.  The Metal Separation Module consists of a large Vibratory Feeder that delivers material onto a strong Drum Magnet before passing over an Eddy Current Separator.

Bunting Magnetics Europe Ltd, a leading Magnetic Separator manufacturer based in the UK, worked closely with Recapture Plastics to provide a range of metal separation equipment that would ensure a metal-free final product.

Recapture Plastics developed and built the new plastics recycling plant in Rochester, Kent.  The plant is designed to handle up to 25 tph infeed of recycled plastic material with a view to future expansion.  Plastic is sourced from across the UK, mostly in baled form, and the operation is one of a few recycling plants with the ability to process and separate the materials effectively.

The plastics recycling process designed by Recapture Plastics has a number of key stages.  Initially, the bales of mixed plastics are broken up and shredded to reduce the particle size and liberate materials to enable optimum separation.  The shredded plastic mix then passes over the Bunting Metal Separation Module where a strong Drum Magnet removes ferrous metals and then an Eddy Current Separator ejects non-ferrous metals.

The Bunting Drum Magnet is designed with strong permanent Rare Earth Magnets configured in an axial magnetic field.  This enables high levels of separation with a minimal loss of clean material.  The shredded plastic is evenly fed onto the top of the Drum Magnet by a large Vibratory Feeder with out-of-balance motors.  Any ferrous and weakly magnetic material becomes magnetically attracted to the surface of the non-magnetic stainless steel shell by the stationary magnet element inside the Drum Magnet.  Attracted metal then moves with the rotational motion of the non-magnetic outer shell until it leaves the magnetic field and is deposited in a waste chute directly underneath the drum, away from the shredded plastic.

The ferrous-free plastic fraction falls evenly onto the conveyor of the Bunting Eddy Current Separator, which transports it into the rotating magnetic field.  Non-ferrous metals, such as aluminium, brass and copper, are propelled away from the rotating magnetic field and non-metallic shredded plastic over a strategically-placed adjustable splitter.  This enables a clean separation.

The cleansed plastic fraction continues through the process, which includes polymer sorting and further size reduction before passing through a Bunting Quicktron Metal Separator.  This final stage of metal separation is positioned to remove any metal freed during the second stage of shredding.

The shredded plastic falls down an inlet pipe into the Electromagnetic Field of the Metal Separator search coil.  Any metal alters the high frequency magnetic field generated by the search coil signalling contamination and a signal is sent to the double actuating air cylinder of the reject assembly underneath the unit.  The metal contamination, with a minimal amount of clean material, is then diverted out of the clean material flow and into a waste collection area.  Often this is recycled to reduce product loss.  The reject time is adjustable to suit each specific application.  After the metal has been removed, the reject flap returns to the normal position, once again allowing clean product to flow through.

The metal-free plastic moves onto a washing stage and colour sorting prior to bagging for shipment.

The plastics recycling plant starting processing material in November 2015, only 3 months after Recapture Plastics moved into the building.

Neale Buttery, Recapture’s Operation Manager, explained the reason behind selecting Bunting equipment:

“We have worked with Carlton [Hicks – Bunting’s UK Sales Manager] before and knew that he understood what we were looking for.  This whole operation depends on producing metal free, clean plastic and we felt that the Bunting equipment would make sure we achieved that goal.”

Simon Ayling, Bunting Europe’s Managing Director added:  “The successful installation and operation of any Magnetic Separation or Metal Detection equipment is down the supplier and user working together.  Neale and Roger [Evans] were very clear in explaining what they wanted and that helped us select the best equipment.  Carlton’s experience in the recycling industry was invaluable in ensuring we met their expectations.”

Bunting Magnetics manufactures and supplies a wide range of Metal Separators for the recycling industry including Magnetic Separators, Eddy Current Separators, and Metal Detectors.  The company will be exhibiting at both Waste 16 (Salford, UK 9th June 2016) and RWM (NEC, Birmingham 13-15 September 2016).
