What is a twin screw extruder?

The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its wide feeding system(volumetric feeder or gravimetric feeder)good mixing and plasticizing performance, exhaust performance, polymer reaction, etc., it has been widely used in extrusion or pelletizing products.

Working principle of twin screw extruder:

  1. The laws of changes in the physical state of polymers in the extrusion process, the truth and laws of conveying and exhausting of solid melts, and the establishment of mathematical and physical models are used to guide the design of twin-screw extruders and the optimization of extrusion processes.
  2. Find out the real state of physical state change, mixing form, structure change process and the relationship between the final mixture and properties of two or more polymers and materials during extrusion.
  3. As a twin-screw extruder, the internal relationship between the reaction process, speed, performance and screw configuration and operating conditions during reaction molding is extruded, and a model is established to guide the reaction molding extrusion.

Advantages of twin screw extruders

1. Good self-cleaning: There is a speed difference at the meshing position between the twin screws. Under mutual friction, the occurrence of material stagnation can be reduced, and the self-cleaning properties of the co-rotating twin-screw are stronger.

2. For experimental research or mixing of thermosetting plastics with poor fluidity, in order to facilitate observation, or to clean the barrel, the twin-screw barrel can be made into a split structure.After opening the barrel, you can observe the melting, plasticizing and mixing state of the material, meanwhile,observe the wear degree of the threaded elements, the inner liner of the barrel and other components at any time, so as to carry out timely and effective replacement, and avoid product waste caused by damaged components.

3. Reduce manufacturing cost. Since the barrel and screw of the twin-screw are of modular structure, it is only need to replace the worn copper and some screw elements. Comparing with the single screw, the entire screw or barrel needs to be replaced. Maintenance costs are greatly reduced.

4. High torque, high speed. By observing the development trend of twin-screw extruders, we can see that this field is currently developing in the direction of high torque, high speed, and low energy consumption.

5. High output and high quality. Compared with the single-screw extruder, the twin-screw extruder, especially the intermeshing twin-screw extruder, performs better in the solid and melt conveying of materials. High output, high quality, high efficiency and other advantages.
