One of the world’s most comprehensive ranges of metal separators will feature at the international K 2022 plastics and rubber trade fair. On the interactive stand B01 in hall 10, Bunting is displaying working examples of magnetic separators, metal detectors, and an Eddy Current Separator specifically designed for processing plastic waste.

Plastics manufacturing relies on the feed material, whether virgin or recycled, being metal-free. Metal contamination is costly both from equipment damage and production downtime. With a continued increase in the use of recycled material, both from internal and external sources, the need for optimum metal separation has never been more acute.

The magnetic separators and metal detectors on display on the Bunting stand at K 2022 are specifically designed for each stage of the process. Commonly used together in a Cleaning Station configuration, the magnetic separators attract and remove ferrous metals leaving the metal detectors to focus on non-ferrous metal removal.

The five Metal Detectors displayed and operating on the Bunting stand at K 2022 are designed for installation at different stages within the manufacturing process and to handle specific materials. The quickTRON 05, quickTRON 03R, and HS9050/9100 Metal Detectors detect and separate all metal contamination in free-fall applications. The Machine Mounted Metal Separator (MMS) is designed to operate in choke applications, and is mounted directly on top of Injection Moulding Machines. The reject mechanisms automatically remove metal contamination whilst minimizing loss of good product. The pTRON Metal Detector detects and rejects all ferrous metals, non-ferrous metals, and stainless-steel metal contamination within enclosed pipe systems. With a double pinch valve, these metal detectors prevent loss of pressure or vacuum when installed in pressurised, suction, or vacuum conveyor lines.
The global focus on the recycling of plastic waste continues to drive innovation. For removing the small non-ferrous metal found when recycling polypropylene, PET, or film, Bunting developed the High-Intensity Eccentric (HIE) Eddy Current Separator. The Eddy Current Separator (ECS) utilises magnetic forces to physically repel non-ferrous metals and enables separation from non-conductive materials.
On stand B01 in hall 10 at the K 2022 show, visitors will see a production-size Eddy Current Separator and Drum Magnet separating small ferrous and non-ferrous metal from shredded PET. Bunting invites visitors to bring samples to the show for testing.
The Eddy Current Separator works perfectly prior to Bunting’s revolutionary ElectroStatic Separator. The ElectroStatic Separator enables the removal of ultra-fine conductive metals.
Complimenting the range of Magnetic Separators and Metal Detectors are Bunting’s Shredder Feeder and Discharge Conveyors, which are designed specifically for material handling in the plastics industry. The conveyors, with either an integrated magnetic separator or metal detector, provide optimum controlled product feed to and metal damage protection for a shredder or granulator. The conveyors are particularly suited for installation in lines reprocessing in-house plastic rejects, and plastic waste in a recycling plant.
Any plastics producer or recycler with a metal contamination issue is invited to visit the Bunting stand and talk with one of Bunting’s experienced internationally-based sales team.
