Counter-rotating twin screw extruder

Unique Counter Rotating Twin Screw Extruder

Actually more than PVC applications

To understand them better!

Probably most people have the traditional understanding of counter-rotating twin screw extruder.

Low speed and low shear are the most points for such twin screw extruder. Anyway, such typical machines, presently, are just successfully applied in PVC process and some other special processes.

Along with the deep and full understanding of the advantages and disadvantages of such counter rotating twin screw extruder, we developed the new screw profile to decrease the serious intermeshing forces and hence to make it possible run at higher speed. Consequently, we could find more and more positive features for such machines.

►higher productivity
►better and controllable mixing effect
►stronger degassing capacity
►unique elagation mixing available


TDY-A, the best extruders for PET processing!
     - Either for direct extrusion without predrying process or recycling extrusion process

Near-to-zero IV drop now is practicable for screw extrusion process. This great point is mainly contributed from some very unique features in high speed twin screw extruder. Among of these features, the most important point is the larger exposed area to extreme vacuum during extrusion. The most sections along the two screws are exposed and this will cause better removing of low molecular weight materials. Also, the gentle shearing along whole screw could avoid overheating very well.
Strong taking-in features and high speed condition make this twin screw extruder very advantageous for those fluffy materials, like film scrapes, bottle flakes, chopped fibers. Such system could avoid the agglomeration units to avoid extra energy consumption.

New concept - Modular counter-rotating twin screw extruder available

To adapt more and more different compounding processes, USEON developed the modular extrusion units for flexible regulation of different screw profiles. This greatly make it easy to change the screw design. Actually, some typical process require such function, like WPC process, reactive extrusion where the RTD and mixing strength are variable.
