Bunting to debut stainless steel separator at Recycling Technik event

High intensity separation conveyor will be on display at German show.


Bunting Magnetics Europe Ltd. based in the U.K., reports that it will debut its new High Intensity Separation Conveyor (HISC) stainless steel magnetic separator at Recycling Technik 2015, to be held in Dortmund, Germany 4-5 November 2015.

The Stainless Steel Separator will be on display on Bunting’s stand T05-7 along with a range of other metal separation equipment.

Bunting reports that it developed the high intensity magnetic separator designed specifically for stainless steel separation after extensive research and development.

The company points out that there are five types of stainless steel, with ferritic, martensitic, duplex and precipitation hardening (PH) all being magnetic, and austenitic being weakly magnetic in certain circumstances.


The company explains that on the High Intensity Separation Conveyor, magnetic susceptible stainless steel is separated using a complex, unique and exceptionally strong magnetic pulley configuration. In operation, a material mix of nonmetallic and stainless steel is transported along a two-pulley conveyor belt into the high intensity magnetic field of the head pulley.

According to Bunting, in the intense separation zone, weakly magnetic stainless steel is attracted and separated from nonmagnetic material. The ability to separate the weakly magnetic stainless steel results from 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, enabling even stainless steel with very weak magnetic properties to be attracted and separated, the company says.

Bunting says the separator’s design, which took 12 months to perfect, was undertaken by experienced staff engineers.
The first European installation of the new separator was commissioned in September 2015, Bunting says. According to Bunting, there has been a great deal of interest from companies recycling UPVC (unplasticized polyvinyl chloride) window frames, where stainless steel removal is a huge issue.

On their stand at the Recycling Technik 2015 show, Bunting will be demonstrating a working HISC. The company will also be promoting a 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.

Carlton Hicks, Bunting’s U.K. sales manager explains, “Following the excitement and incredible interest generated at the recent RWM (Waste & Recycling) exhibition in Birmingham, U.K., exhibiting at Recycling Technik in Dortmund gives us a fantastic opportunity to introduce this new magnetic separation technology to companies in Germany and mainland Europe. The new stainless steel separator is the third step in a metal separation process. Firstly we remove the strongly magnetic materials with an overband magnet, drum magnet or magnetic pulley. Secondly, we recover and remove the nonferrous metals with the eddy current separator. Up until now, there have been difficulties in practically and economically removing the stainless steel, which is now possible with the High Intensity Separation Conveyor.”
