Abstract: A highly-dispersive mixing twin-screw element was designed based on the meshing theory of intermeshing co-rotating twin-screw extruders. The flow fields for three screw configurations were simulated by Polyflow. Experimental study was carried out in an intermeshing co-rotating twin-screw extruder. It was found that the screw element with a staggering angle of 150 ° had a better dispersive mixing performance than those of 30 ° and 90 °.

Key words: intermeshing co-rotating twin-screw extruder, dispersive mixing, twin-screw element
