Twin Stage Twin Screw Extruder

Kelongweier’s two-stage extrusion system: the first stage is high speed and high torque co-rotating twin screw extruder and the second stage is single screw extruder to form a two-stage compound extrusion system.

Applications of Kelongweier’s Two Stage Extruder:

PVC Cable Material and XLPE Peroxide Crosslinking Material
Soft PVC Medical Material
Hard PVC Products
EVA Foamed Shoe Bottom Material
PE Low Smoke Halogen Free Resistance Fuel

Main Features of Kelongweier’s Two Stage Extruder:

Plasticization, mixing and homogenization of twin screw processing section

Open melt feeding single screw extruder without backpressure, meanwhile exhaust and devolatilization can be carried out at the same time.

Soft extrusion of materials through the template of single screw extruder

Air-cooled granulation, eccentric water mist granulation, stretch granulation and water ring granulation can be selected according to material properties.

Smaller power and area

Fully automatic raw material mixing and granulation process to reduce labor costs

Easy to operate and stable to run
