Co-Rotating Twin-Screw Extruders: Fundamentals, Technology, and Applications (#0744)
By Klemens Kohlgruber, 2007, 350 pages
Price: $102.00 / SPE Member $85.00






Well-rounded knowledge of machines, processes, and material behavior is required in order to design twin-screw extruders for economically successful operation. This book provides basic engineering knowledge covering the most important technical requirements and provides examples based on actual practice. Better understanding of the process is emphasized, as this is a prerequisite for optimizing twin-screw designs and operating them efficiently.
