CK Group, based in Lincolnshire, has invested several hundred thousand pounds in processing equipment to improve the quality of the plastic regrinds it sells to compounders and manufacturers, which use it for direct injection moulding and extrusion.
The optical sorting line was installed at its Binbrook processing plant last December and has since gone through testing and commissioning. It is now being used to optically sort more than 150 tonnes of recycled plastic regrinds a week.
Different regrinds and pellets can be identified by the sorter by colour, material type and granule size, and it rejects those chosen to be undesirable. Trained operators can amend settings on the cameras to detect and eject the unwanted fraction to leave a polymer stream to suit customer requirements, such as a mixed colour regrind with zero black fraction, suitable for light coloured compounds.
Chris Collier, CK Group commercial director, said: “Combined with our investment in laboratory testing facilities, 20 tonne blenders and a wash line, this acquisition adds to our flexibility to handle a diverse range of regrinds and to give our customers what they want and need to be competitive.”
