The two-day event is taking place from 14-15 June in Essen, Germany. Bunting's team can be found at booth B929, eager to discuss proven metal separation technologies, including FF drawer filter magnets and eddy current separators.

‘Secondary plastic, whether post-consumer or production scrap, commonly contains metal contamination. This material can damage equipment such as granulators, extruders and injection moulding machines,’ Bunting points out. The company has developed a wide range of equipment to detect and separate such metal and prevent costly wear and repairs.

The FF drawer filter magnet is an ‘industry standard’ for the plastics sector, featuring ‘ultra-strong’ neodymium tube magnets, mounted in a grid formation, to attract and securely hold even the smallest and weakest magnetic particles. These are easily installed above injection moulding machines and prior to granulators.

Meanwhile, the quickTRON range of gravity free-fall metal detectors can detect and separate metal present in granulated plastic, often directly after the FF Drawer Filter Magnet as seen in Metal Cleaning Systems. Pipeline Style Metal Separators (pTRON) detect and then reject any kind of metal from an enclosed pipe system.

Recent projects include the installation of a metal separation module at HML Recycling in Accrington, UK, for a new line recycling perfume bottle tops. The shredded plastic tops are contaminated by ferrous and non-ferrous metal, which Buntings helps to sort out.
