YILI Conical Twin-Screw Extruder: The conical twin-screw extruder is an efficient mixing and extrusion device. The machine has the characteristics of small shear rate, easy decomposition of materials, uniform mixing of plastic, stable quality, high output, wide application range and long life service.

The counter-rotating conical twin screw extruder is ideally suited for quality control, product development and research applications.

All the screws allow a uniform forward flow regardless to the degree of flight filling, feeding uniformity, polymer flow characteristics, or back pressure. The counter rotating chamber produces a milling action between the screws similar to a calendering process.



The Twin Screw Extruder are mainly used for the processing of the soft/hard PVC pipes, PVC profiles, PVC cables, PVC transparent bottles as well as the other polyolefin products, especially the direct processing of the plastic/powder materials.

Optimally dimensioned drive concept, with AC drive in the standard version.

Robust gearbox ensures low maintenance costs and long service life.

Synchronization speed for main drive, starve feeder and haul-off.

Double Vacuum Storage tanks (for easy cleaning during production).

Energy saving and easy to maintenance.
