Recycling extruder designed for reprocessing film, fibers and mats


About 60 visitors to the Recycling & Compounding TecDay organized by KraussMaffei Berstorff and EREMA received insider information about state-of-the-art technologies, innovative machinery and unparalleled services around plastics recycling. The main focus of the TecDay was placed on the EdelweissCompounding concept composed of an EREMA recycling extruder and a KraussMaffei twin-screw extruder. Plastics recycling and compounding companies can use this line for re-compounding tests performed under real production conditions. "For recycling specialists, compounding companies and university representatives, this event offered an ideal opportunity to participate in a live demonstration of premium-quality plastics recycling," reports Ralf J. Dahl, Head of the Twin-Screw Extruder Division at KraussMaffei Berstorff. "Customers and other interested guests used this unique platform for in-depth discussions with experts and industry colleagues and took a closer look at the EREMA/KraussMaffei Berstorff production solution."

The EdelweissCompounding line with the EREMA recycling extruder designed for reprocessing film, fibers and mats was the focal point of the TecDay. During the event, post-industrial PP film scraps with different degrees of contamination were converted into a PP compound with a 30 per cent talc share in a 2-stage extrusion process. The line is rated for filler contents of up to 80 per cent and a throughput range of up to 1,000 kg/h.

The recycling/compounding line comprises an EREMA recycling extruder (COEREMA® 1108T), melt filter and melt pump, a KraussMaffei Berstorff ZE 60 R UTXi twin-screw extruder and a water-cooled die face pelletizing system.
Technical lectures held by Interseroh Dienstleistungs GmbH, Borealis Polyolefine GmbH, Veolia Polymers NL B.V., EREMA Engineering Recycling Maschinen und Anlagen GmbH and KraussMaffei Berstorff rounded off the TecDay. "After the TecDay, the line can be used by EREMA and KraussMaffei Berstorff customers for tests performed under real production conditions," says Ralf Dahl. "Our customers will not only benefit from the excellent performance of the extrusion line, but also from the extensive support offered by EREMA and KraussMaffei Berstorff in the field of process improvement, screw and machine development and the optimization of the entire production sequence."
