New Stainless Steel Separator Operating At RWM 2015

On stand 5T152-V153 at RWM 2015 (NEC, Birmingham 15-17th September 2015), Bunting Magnetics will be displaying and demonstrating new Magnetic Separation Technology with the High Intensity Separation Conveyor (HISC), which has been specifically developed to separate stainless steel.

Separating and recovering valuable Stainless Steel is a problem faced by recycling companies globally. Following a prolonged period of research and development, Bunting Magnetics has developed and is launching a sophisticated and high intensity magnetic separator specifically to solve the problem of stainless steel separation.

There are 5 types of stainless steel, with Ferritic, Martensitic, Duplex and Precipitation Hardening (PH) all being magnetic, and Austenitic being weakly magnetic in certain circumstances.

On the High Intensity Separation Conveyor, magnetic susceptible stainless steel is separated using a complex, unique and exceptional strong magnetic pulley configuration. In operation, a material mix of non-metallic and stainless steel is transported along a two pulley conveyor belt into the high intensity magnetic field of the head pulley. In the intense ‘Separation Zone’, weakly magnetic stainless steel is attracted and separated from non-magnetic material.

The ability to separate the weakly magnetic stainless steel is due to the design of the magnetic head pulley. The design and configuration of the high intensity permanent Rare Earth Magnets in the head pulley produce a unique magnetic field and thus enables even stainless steel with very weak magnetic properties to be attracted and separated. The design work was undertaken by experienced Bunting engineers and took over 12 months to perfect.

There has already been a huge response from recycling companies in the USA and UK, with the first European installation planned for August 2015. In particular, there has been a great deal of interest from companies recycling UPVC window frames, where stainless steel removal is a huge issue.

On their stand at the RWM show, Bunting will be demonstrating a working High Intensity Separation Conveyor. Carlton Hicks, Bunting’s UK Sales Manager explained:

“Seeing is believing and we are thrilled to be exhibiting newly developed equipment that addresses the age old problem – separating and recovering stainless steel. Being able to launch this in Europe at RWM is fantastic as we know that the show attracts visitors from across the world. Of course, the key to any successful separation is sizing and preparing the material before it is processed on the High Intensity Separation Conveyor and this means recovering and removing the magnetics using Drum Magnets and Pulley Magnets. Also, to reduce the loading and enhance the level of separation on the High Intensity Separation Conveyor, it is best to first pass the material over an Eddy Current Separator to recover non-ferrous metals. The Eddy Current Separator doesn’t recover stainless steel, but we will then be left with a material mix which includes the valuable stainless steel and non-metallic materials. RWM will be a very exciting show for us.”

On the stand at RWM, Bunting will be promoting a full range of Metal Separation equipment for all sectors of the recycling industry, including Overband Magnets, Drum Magnets, Pulley Magnets, Plate Magnets, Grate Magnets and Metal Detectors. With a collective 30 year plus experience in supplying the recycling industry with metal separation solutions, the Bunting technical sales team will be available to discuss any aspect of metal recovery and separation.
