Bunting-Redditch Launches New Shredder Feeder Conveyor

At Interplas 2021, Bunting-Redditch launched the new Shredder Feeder Conveyor, which combines with either a magnetic separator or metal detector to protect a shredder or granulator from metal damage.

Specifically designed for recycling plastics, both in-house regrind and from secondary sources, the Shredder Feeder Conveyor provides an even and controlled feed into a shredder or granulator. The design specifically accommodates a metal detector or magnetic separator.

Preventing metal contamination damage

Shredder damage from metal contamination is costly in both repair and production downtime. Materials fed on the Shredder Feeder Conveyor pass through a metal detector or under a magnetic separator to find and remove such metal. Such protection prevents shredder damage and metal contaminants from being reduced into smaller particle sizes, which become more difficult to remove.

Shredder Feeder Conveyors are also located post-shredding and prior to feeding the material into a granulator or extruder. Identifying and removing metal at this stage protects the granulator and extruder from damage and ensures the quality of the regrind prior to internal use or external sale.

The Shredder Feeder Conveyor design accommodates different designs of magnetic separator, including overband magnets, suspension magnets, plate magnets, and pulley magnets. The design of the conveyor limits the potential magnetisation of the supporting frame to ensure the clean discharge of captured ferrous metal.

Different conveyor designs often detrimentally affect the performance of a metal detector. The Shredder Feeder Conveyor specifically includes design features to minimise any metal detector interference and ensure optimum detection at all times. The application and nature of the metal contamination determines the selection of either an underbelt or tunnel-type metal detector. The optional extra of an automated reject system enables the removal of metal contamination without disrupting the material flow. On identifying metal in the material, the metal detector transmits a signal to a reject flap mounted at the end of the conveyor. The reject flap redirects the contaminated material into a separate collection area.

The Shredder Feeder Conveyor further expands Bunting’s range of equipment for plastics and recycling companies.
