Extrusion Asia Edition 1-2023

ZSK 58 Mc 18 extruder will be outfitted with a Coperion K-Tron K-ML-SFS-KT20 twin screw loss-in-weight feeder. In addition to compounding and recycling, Coperion extruders are suitable for the production of bioplastics. This process plac- es very high demands on the extrusion system due to the diver- sity of base polymers being used and the variety of recipes. Co- perion has already realized numerous systems for the produc- tion of bioplastics and therefore has comprehensive engineer- ing know-how in designing the process steps needed to achieve the required mechanical properties of the bioplastic end product. The STS 25 Mc 11 laboratory extruder that Coperion will show at Chinaplas, has a 25 mm screw diameter and features a simple design. It is operator-friendly and easy to clean. By having the same screw diameter ratio D o /D i of 1.55 and the same maxi- mum specific torque Md/a³ of 11.3 Nm/cm³ as the entire STS Mc 11 extruder series, production parameters can be reliably sca- led up to a larger STS model. To extend the process window, Coperion has increased the screw speed of the STS 25 Mc 11 to 1,200 min -1 . This way the laboratory extruder is ideally suited for recipe development and basic scientific research with small batch sizes of 2 kg and achieves throughput rates of up to 110 kg/h. The STS 25 Mc 11 which Coperion will exhibit at Chinaplas will be shown with a Colormax Systems C/S-LW- NT28 twin screw loss-in-weight feeder. Complete plastics recycling plants from a single source Together, Coperion and Herbold Meckesheim realize entire plants for plastics recycling. From mechanical processing – shredding, washing, separating, drying and agglomerating of plastics – to bulk material handling as well as feeding and ex- trusion all the way to compounding and pelletizing, their sys- tems cover the entire process chain for reclaiming plastics. Coperion and Herbold Meckesheim achieve solutions for me- chanical recycling of post-industrial and post-consumer waste, chemical recycling, solvent-based recycling, and deodorization, tailored to the type of plastic being recycled. Together, they will be showing a PET recycling plant simulation at Chinaplas, demonstrating their expertise in numerous plastics recycling processes. Booth visitors can look directly into the process steps and view the construction and functionality of key technolo- gies. Coperion K-Tron feeders for maximum flexibility Also on display will be a high-accuracy Coperion K-Tron K2-ML- D5-T35/S60 quick change feeder, featuring the ActiFlow™ smart bulk solid activator and Electronic Pressure Compensa- tion (EPC) in combination with a 2400 Series vacuum receiver for refill. The T35/S60 quick change feeder (QC) on display is designed for applications requiring quick changeover of materi- als and convenience of fast cleaning. The QC feeder allows for fast removal of the entire feeding module with screws in place for replacement with a second unit. Twin and single screw feeding modules are available. The ActiFlow™ smart bulk solid activator offers an innovative method to reliably prevent bridging and rat-holing of cohesive bulk materials in stainless steel hoppers without internal hop- per agitation. The smart flow aid applies gentle vibrations to the hopper wall, hereby carefully activating the contained ma- terial with the optimal amplitude and frequency. It is designed specifically to work with Coperion K-Tron’s line of gravimetric loss-in-weight feeders. 2400 Series vacuum receivers provide a high-capacity sequenc- ing system primarily used where larger conveying rates or long distances are required, in applications with one or multiple des- tinations. They are designed to high quality standards for pneu- matically conveying powder, pellets and granular materials for most industries. Conveying rates range from 327 to 6,804 kg/h (720 to 15,000 lb/h). The 2415 pellet receiver will be on display at Chinaplas 2023.
