دانلود کتاب Co-Rotating Twin-Screw Extruders - Fundamentals, Technology, and Applications

Co-rotating twin-screw extruders are used in many branches of industry for producing, preparing, and processing highly viscous materials. They find a wide variety of applications especially in the plastics, rubber, and food industries. Co-rotating twin-screw extruders usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Well-founded knowledge of machines, processes, and material behavior is required in order to design twin-screw extruders for economically successful operation. This book provides practitioners with basic engineering knowledge regarding twin-screw extruders. It covers 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. Content:• Front Matter • Preface • Table of Contents 1.
