The article studies the melting process in a channel of a single-screw extruder to reduce the energy consumption and improve the efficiency of melting of a polymer. The article presents the most common methods of extrusion modelling, which differ by the interpretation, various factors, and accuracy of the process.
There is an analysis of the main approaches for obtaining the quantitative result of melting at screw extrusion. In order to intensify the process and reduce the overall length of the melting zone we have suggested the implementation of the model of variance melting at single-screw extrusion for the account of the "hungry" power, i.e., at a limited supply of the material to the charging area.
The authors provide the dependences to determine the temperature distribution within granules. The algorithm, which permits to calculate the time of a granule in the melting zone, was suggestedReferences
