Effect of the Screw Flight On Melt Temperature, Energy Use

摘要

Most discussion of screw design is centered on the channel depths, or whether the screw has a barrier section, wave section, mixer, and so forth. You seldom hear much about the effect of the flight on the design. Out of convenience, flight width and clearance are usually chosen as approximately 10% of the screw diameter for the width and 0.1% of the diameter for the radial flight clearance. Screws smaller than 2 in. or larger than 10 in. may not follow that practice.
