## Abstract A fully‐predictive steady‐state computer model has been developed for a single‐screw plasticating extruder. Included in the model are a model for solids flow in the feed hopper; a variation of the Darnell and Mol model for the solids conveying zone; a variation of Tadmor's melting model

A theoretical model is developed to describe the melting mechanism in the transition zone of a screw extruder. The plug flow profile of the granules in the screw channel is calculated as a function of the screw speed, the barrel temperature and the mass flow rate. The assumptions made in this model
