Abstract

A simplified theoretical model of the melting process, based on T admor' s analysis of the Maddock mechanism, is used to investigate the possibilities to increase the melting capacity of an extruder. Some screw constructions are discussed. The analysis leads to the conclusion that the best way to improved performance is to increase the heat flux to the melting front, which in turn is best achieved by increasing the dissipative heat generation in the melt film. This may be realized in a new type of melting element, the melttorpedo, of which the working is explained. Preliminary tests indicate that this element provides good possibilities to improve efficiency of single screw extruders.
