Counter-rotating Twin Screw PVC Extruder

counter rotating twin screw pvc extruder ,special for pvc pelletizing and pvc profile extrusion

  • TSE-75B
  • HS

counter-rotating twin-screw extruders are widely used in extrusion molding and batch granulation.

Tightly meshing counter-rotating twin-screw extruder for PVC profile extrusion

The shear rate is limited to [γ] = 6 to 8S-1. The maximum linear speed of the screw

V=7~8m/min for the maximum linear speed of the screw when it is extruded from PVC pipe

V = 10 to 12 m/min. Therefore, it is often operated at a lower speed.

Meshing co-rotating twin-screw extruder, widely used in polymers

Modification: blending, filling and fiber reinforcement, compounding or mixing. also may

Used for extrusion of shaped articles, but rarely used to process profile products.

The allowable shear rate is around [γ] = 60 to 140 S-1.

The screw line speed V=30~50m/min,

The maximum V = 160m / min.

High-speed meshing co-rotating twin-screw extruders are commonly used for materials

The compounding and extrusion and venting operations as a continuous chemical reaction. This type of squeeze

The speed of the output is in the range of 300 to 600 r/min.
