Modular twin screw extruder screw elements are individual functional components assembled axially on the screw shaft. Unlike one-piece screw designs, modular systems allow each element to perform a dedicated role within the extrusion process.
In a typical configuration:
Conveying elements are responsible for transporting material forward along the barrel.
Kneading elements focus on intensive mixing, dispersion, and homogenization of materials.
This modular design philosophy makes it possible to precisely control material flow, residence time, and mixing intensity throughout the extrusion process.

The key advantage of modular screw elements lies in their flexibility. By adjusting the type, number, and arrangement of screw elements, the screw structure can be customized for specific applications.
This allows engineers to:
Optimize processing for different raw materials
Adjust mixing intensity without changing the entire screw
Balance throughput, energy consumption, and product quality
ZHITIAN applies long-term extrusion experience and screw configuration know-how to design functional screw layouts that align with real processing requirements rather than theoretical parameters alone.
Modular twin screw screw elements are widely applied in:
Polymer compounding and modification
Masterbatch production
Chemical and reactive extrusion
Food and feed processing
Recycling and devolatilization processes
They are suitable for both R&D extrusion lines and large-scale industrial production.
Modular flexibility: Easy adjustment of screw configuration
Function-oriented design: Each element serves a clear processing purpose
Process optimization: Precise control of conveying and mixing
High compatibility: Suitable for mainstream twin screw extruders
Stable performance: Consistent product quality across applications
Selection depends on material properties, desired mixing level, and process goals rather than machine size alone.
Conveying elements transport material forward, while kneading elements provide intensive mixing and dispersion.
Yes. Modular design allows flexible adjustment of element types and sequences for specific applications.
They are suitable for plastics, chemicals, food, feed, and recycling industries.
