Selection Method for the Screw Length-to-Diameter Ratio in Extruders

Generally, the selection can be made based on material characteristics and production efficiency.

The Impact of Extruder Screw Compression Ratio on Production Efficiency

The compression ratio of an extruder screw refers to the volume ratio between the first flight channel in the feed section and the last flight channel in the homogenization section. The compression ratio affects the production efficiency of a twin-screw extruder through the following aspects:
