Research on pellet conveying in single-screw extruders was presented at the recent 24th International Colloquium of the Institute for Plastics Processing (IKV) in Aachen, Germany. The project, presented by engineering graduate student Micha Scharf, is gathering data that will permit computer software to be developed for simulating what happens in the feed zone of an extruder. So far, only melting and metering have been simulated. The project determined the coefficient of friction of pellets on the screw by measuring the radial and axial forces on the pellets. scharf@ikv.rwth-aachen.de
