Comparison of different types of Exhaust Screw Of The Extruder

1. Single screw exhaust screw
Features: relatively simple structure, low cost, suitable for some extrusion processes that do not require particularly high exhaust.
Advantages: easy to maintain and replace, suitable for small-scale production or trial production stage.
Limitations: relatively low exhaust efficiency, may not work well for materials with high viscosity and high gas content.
2. Twin screw exhaust screw
Features: It has two intermeshing screws, which can provide stronger shear force and mixing effect, which is conducive to the exhaust of gas.
Advantages: high exhaust efficiency, suitable for processing materials with high viscosity and high gas content, and extrusion processes that require high mixing effects.
Limitations: complex structure, high cost, relatively difficult maintenance and replacement.
3. Multi-screw exhaust screw
Features: an extruder system including three or more screws, providing higher mixing efficiency and exhaust capacity.
Advantages: particularly suitable for processing complex materials or production processes that require extremely high exhaust efficiency.
Limitations: Highest cost, most complex structure, and most difficult to operate and maintain.
