| Abstract: | Using the scale-up theory for single screw extruder for reference,nine typical methods of scale-up were evaluated synthetically with the method of equivalent diameter.By investigating technical data of ZSK Mc series compounders of CW&P,the application of scale-up to engineering practice was analyzed.The strategy of scale-up for large co-rotating twin-screw extruder was given,namely screw peripheral speed should keep constant. |
