Abstract
Expanding the general knowledge of the extrusion process in a co-rotating twin-screw extruder requires several parameters to be determined, among them the residence time distribution (RTD). This contribution introduces an optical measurement setup for acquiring the residence time density and distribution function. Based on our measurement results, we derive the influence of the rotational speed of the screws, mass flow rate and of different types of screw configurations on residence time.
