Bunting Magnetics  Europe, Berkhamstead, UK, has in recent years supplied metal separation equipment (both magnetic separators and metal detectors) to Renmar Plastics Machinery in Wellingborough. Activity in plastics recycling has increased significantly for Renmar since 2017.  Owing to the nature of the secondary material, there is often a higher proportion of contamination including metal particles.  There is also a drive towards producing smaller-sized, higher-quality granulated plastics from waste.  This raises the value of the product, but increases the possibility of equipment damage due to metal contamination.  The selection and installation of the optimum design of metal separator is critical to the successful operation of the recycling plant.

Kevin Horne, director of Renmar, has forged a close relationship with Bunting in order to provide customers with up-to-date and technically advanced metal separation solutions.  Bunting engineers are readily available to discuss issues and visit the site. Equipment recently supplied by Bunting includes: a small permanent overband magnet mounted across a conveyor to lift and remove ferrous metals from shredded plastic; drawer filter magnets, as part of a virgin plastic process, for removing millimetre-sized ferrous material from beads before a free-fall metal detector identifies and ejects non-ferrous metal contaminants; and a meTRON 05 underbelt metal detector to identify needles in plastic sheet produced from shredded recycled materials.

Renmar and Bunting are both members of the British Plastics Federation, promoting best practice in the industry. www.buntingeurope.com
