ABSTRACT

Increasing screw speed is a possible approach to improve the performance of a single screw extruder but itchallenges the processing technology and the material processed. Apart from difficult melting, the feeding of the screw with granules is complicated. This results in partially filled screw channels. In the following, the resin transfer depending on the screw speed is investigated and analyzed by means of the simulation program EDEM, which is based on the Discrete Element Method.
