Extruder Principles and Operation

Thoroughly updated since the publication of the first edition, with new chapters on die design for operators, solids conveying and melting and twin-screw extruders, this book bridges the gap between theoretical studies and the practical experience of the processor in the extrusion of thermoplastic polymers and rubbers.
Theoretical discussions generally give little attention to practical considerations, such as the conflict between productivity and product quality. Here however the authors give a clear representation of the physical mechanisms on which so much of the polymer processing industry depends, followed by guidance on operational strategies and the likely effects in terms of output, quality, uniformity and stability. Practical information is given on start-up trials, scale-up, product changing, dismantling and cleaning.
Supported by over 40 tables and 176 figures, Extruder Principles and Operation will provide commercial processors with a logical background based on theory and experience, which will help them to obtain the best performance from their equipment, to recognize its limitations and to face new problems with confidence.
