Abstract

Our goal is the determination of the material flow processes around the mixing screws and introducing a new mixing index which can characterize the performance of open mixing screws. The validation of the new discrete element model is demonstrated by experimental results of our self-developed apparatus. To quantify the mixing efficiency of open mixing screws we use the value of mixed volume around the screws. Sensitivity analysis is used to analyze how the different values of leaf diameter, pitch and angular velocity affect the mixed volume.
