Deeply Study of Scale-up Parameters Optimization of Co-rotating Twin-Screw Extruder

Jiang Bo

Abstract

Taking 20 and 72 co-rotating twin-screw extruder as the base model and target model,the effects of different experimental factors i.e.channel depth,screw speed and the clearance between screw and barrel on evaluating indicators(output,energy consumption,the maximum shear stress and mean residence time) were analyzed by combining FEM and orthogonal experiment design.The optimal geometry parameters combination of the target model was obtained.
