Analysis of a Single Screw Extruder with a Grooved Plasticating Barrel

Posted

Single screw extruders with barrier screws, grooved feed zones and grooved melting zones were introduced to the European plastics industry on 1999. These extruders possess a better melting and conveying potential among other advantages, such as a lower melt less have on, temperature, less energy usage and less torque. The aim of this paper is to present a mathematical unit for predicting the melting rate in this sort of extrusion system. Using the classical melting device observed in conventional extruders, it had been possible to review the result of the geometry of the grooved barrel on the melting pace of a polymer. It was found that the grooves on the barrel notably increase the melting rate, in comparison with conventional single screw extruders. A good http://www.useongroup.com/cate gory/foam-extrusion.html contract between theory and experimental info was found.
