Extrusion International USA 5-2019

PREVIEW 66 Extrusion International 5/2019 BUSS’s new COMPEO 88 and COM- PEO 110 kneaders for plastics and elastomers are to be introduced at K2019 in Düsseldorf, adding two higher throughput models to the COMPEO range of compounding systems. They join the smaller COM- PEO 55 which was launched to the market around one year ago. All three models are available with pro- cess lengths from 13 L/D to 25 L/D, the model size indicating the screw diameter in mm. Typical through- puts for processing thermoplastics are 150 to 300 kg/h (COMPEO 55), 600 to 1200 kg/h (COMPEO 88) and 1200 to 2400 kg/h (COMPEO 110). This gives operators the opportu- nity to use a system size optimally adapted to their requirements and thus work with maximum efficiency. BUSS is presenting their current larg- est system, the new COMPEO 110, with a processing length of 18 L/D, including a downstream side feeder alongside their new conical twin screw discharge unit. In this configu- ration the system is suitable, among other things, for compounding filled conventional three- or four-flight kneading elements with new ele- ments comprising two or six flights and to put them to use in any de- sired position within the process sec- tion. Combined with an increase in specific torque, this permits longer mixing zones without any additional increase in energy input. The control system with its OPC UA interface makes COMPEO completely Industry 4.0 compatible. Visitors to the booth will also be able to discover more about COMPEO technology for various applications in the multimedia BUSS CAMPUS. This new platform will be available online after the fair and will allow registered users to download tech- nical videos.

With a process length of 25 L/D, the new COMPEO 88 is optimized for compounding black or colored mas- terbatches and it can if required be fitted with one or two additional side feeders. The first user of such a COMPEO 88 will be a European mas- terbatch manufacturer who is due to take delivery of the new system from BUSS before K2019. Specific advantages of COMPEO compounders include high-intensity mixing, high filler contents and pre- cise temperature control. Assem- bled from standardized modules, they permit cost-effective configu- ration of specifically optimized com- pounding lines for a wide range of processing tasks and temperatures. These range from thermally sensi- tive thermosets to demanding en- gineering polymers with processing temperatures of up to 400°C (750°F).
