Nitrided Screw Barrel for Twin Screw Extruder

Nitrided Screw Barrel for Twin Screw Extruder

Screw elements
Conveying block: It is the most fundamental helical element, whose primary function is to push the material forward along the axial direction of the screw. Through its helical design, it ensures the uniform conveying of the material within the barrel, providing a foundation for subsequent mixing and shearing operations.

Shearing block (meshing block): It is used to enhance the shearing force of the material. It is usually designed as a series of closely spaced disc-shaped elements, arranged at different angles such as 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc. When the material flows through, it generates a strong shearing force, which can break up particle agglomerates, ensure the uniform distribution of additives, and enhance the mixing effect of polymers.
