Abstract

The flow of plastic pellets into the first section of a single screw is frequently neglected when analyzing the solids conveying process in single screw machines. In order to get a better insight into the complex correlations that exist between pellet properties, barrel and screw geomtry a physical-mathematical model is presented. As a result the pellet inflow behavior and the degree of filling in the first channel of the screw can be determined.
