Features of twin screw extrusion granulator

Features of twin screw extrusion granulator

1. The material conveying efficiency of single screw depends on the friction performance of solid material and the viscosity of melt.With double screw extruder, the conveying of the material is carried out by the principle of positive displacement, and there is no pressure backflow.Therefore the material will be easily to feed into compared with single screw extruder.
   

2. Due to the short screw length of the twin-screw pelletizing extruder, the residence time of the material in the twin-screw extruder is shorter.On the one hand, the occurrence of thermal degradation of recycled materials can be avoided, and power consumption can also be reduced.
   

3. Materials are sheared and mixed vertically and horizontally, with excellent homogenizing and plasticizing effects.

4. The machine has excellent exhaust and self-cleaning functions.

5. The flow frequency of the twin-screw granulation extruder is not sensitive to the pressure of the die, and it is more effective for extruding products of large size and area. While the flow frequency of the single-screw granulation extruder is more sensitive to the die pressure.
