Product Description

Conical Twin Screws and Barrels
 

Co-Rotating Conical Twin Screws and Barrels

    Specification:      ø65/ø130   ø72/ø150   ø85/ø186      ø95/ø208   ø115/ø252  
     L/D Ratio:      48:1                                                           
    Applications: pipe,sheet,film,wood-plastic extrusion and soft and hard PVC granulation,cable material granlation,color masterbatch granulation,engineering modified plastic granulation,PP and PE granulation,thermoplastic elastomer granulation.

Advantages:high output,low energy       consumption(compared to the domestic    standard"cone counter-rotating twin-screw extruder" and "parallel co-rotating twin screw extruder",the    output is about two times higher and the power-power consumption-is reduced by 30-50%)  

 

Counter-rotating Conical twin screws&barrels

Specification:ø24/ø52~ø110/ø220

Applications:PVC pipe,plate,sheet,granulation,wood-plastic extrusion.

Inlaid bimetallic layer for the inner hole of the barrel available according to customer requirements.

The compression ratio of screws can be designed according to different raw materials.
