compounder is design to link to its MetaSta- tion drive with integrated modular torque rheometer
50-100 kg/h. Intended for formulation and process development or for sampling and small scale production batches, the new machine offers all the features of the larger Compeo models, including the combination of two, three and four-flight screw elements, to ensure it can provide reliable scale-up of process param- eters to production conditions. “The most important
requirements for a versatile machine are flexibility in terms of processing conditions, materials use, dosing of small amounts and scalabil- ity by means of temperature, throughput, and general processing parameters,” says Krischan Jeltsch, Head of Business Development - Innovation & Digitalization. With demand growing for recycled compounds,
Coperion is building a new testing centre at its Niederbiegen/Weingarten production site in Germany. The Coperion Recycling Innovation Centre is located close to the company’s existing Test Centre for Bulk Solids Handling. “Companies are asking for higher quality
recyclate,” says Frank Lechner, General Manager of Process Technology and R&D at Coperion. “Higher quality wasn’t as much of a concern in the past for recycled material, but it is dominant today. Quality can be improved by using twin screw compounders or proper material handling or best in combination.” Equipment in the facility will include materials

conveying, feeding, extrusion, pelletising, and post-processing. “We want to investigate all parts of the process, including material handling,” says Lechner. “For example, post-consumer recycled flakes, fibres and regrind are more difficult to handle than pellets and virgin powder or flake. We will have the capability to store materials in silos with flat bottom discharge, and will
have a mixer to homogenise different lots.” The feeding equipment will include Smart
Weigh Belt feeders from Coperion K-Tron, and feeders that can handle fluffy, low bulk density material. Extruders in the lab will cover a wide range from 10 kg/h up to 2 tonnes/h. The lines will have capabilities for manual, semi-automatic and fully automated systems and will support scale-up to commercial lines that can run up to 15-20 tonnes/h, according to Lechner. The centre will use in-line testing to ensure a
steady and robust process. Coperion says the intention is to use if for its own research projects and to test new products and processes for customers. It is scheduled to open in the first quarter of 2023.
