Analysis of Maddock and Eagan Mixing Devices for Single Screw Extruder
This study aims to investigate the mixing effect caused by various types of geometry of fluted dispersive mixing elements by numerical simulation. In addition, the clearance between barrier flight and barrel surface, the width of barrier flight and helical angle of barrier flight were varied to investigate their effect on the mixing performance, including the stress and the residence time in the barrier region and the pressure variation at axial direction. Finite element method was used to simulate the mixing section. And carbon black was dispersed in the m-PE phase to investigate the mixing effect.
