How to Determine Screw Geometries for Counter-Rotating Twin-Screw Extruders

Counter-rotating twin-screw extruders have been the predominant process machinery for PVC in the past few decades. These end applications include PVC pipes, profiles, sheets, pellets and more. In this webinar, the screw design concepts for counter-rotating twin-screw extruders will be discussed and the mechanism for counter-rotating twin screw extruders will be explained. In addition, state-of-the-art wear protection for the screws, maintenance and related topics will be covered. In the end, important process parameters for counter-rotating twin-screw extruders will be emphasized and how one can use them to troubleshoot the processing issues for optimized process.
