The single-flighted screw element is primarily used in the feeding section of a twin-screw extruder to increase the storage space in each lead, thus providing greater screw free volume for faster material transfer. This element is particularly beneficial for feeding and conveying powder materials with low bulk density, compensating for decreased output in the twin-screw main unit. The screw element's cross-section is sickle-shaped, ensuring self-cleaning of the screw teeth in both axial and normal directions. Additionally, the design enhances the efficiency of material processing by reducing potential blockages and ensuring consistent material flow.

By optimizing the flow and handling of materials, single-flighted screw elements contribute significantly to the overall performance and efficiency of twin-screw extruders, making them essential components in various industrial applications, particularly in plastics and polymer processing.
