Analysis of a Single Screw Extruder with a Grooved Plasticating Barrel

Posted

Solo screw extruders with barrier screws, grooved feed zones and grooved melting zones were introduced to the European plastics industry on 1999. These extruders have a better melting and conveying capability among other advantages, like a lower melt not as much torque, less wear, much less energy consumption and temperatures. The purpose of this paper is to present a mathematical unit for predicting the melting rate in this sort of extrusion system. In line with the classical melting system seen in conventional extruders, it had been possible to review the result of the geometry of the plastic compounding machines grooved barrel on the melting level of a polymer. It was displayed that the grooves on the barrel notably increase the melting rate, in comparison with conventional single screw extruders. An excellent contract between theory and experimental info was found.
