Conical Rotary Twin-Screw Extruder and PE Pipe Extrusion Experiment Production Line

Product Description

Laboratory Conical Twin-screw Extruder can be integrated by main unit and conical twin-screw extrusion unit. That can be used to simulate real production process in the laboratory.Because of its special structure, the residual material can be cleaned quickly. In the measuring extrusion unit, the sample material begin plastify under practice-oriented conditions and extruded through the die head.Matched well with different die heads ,it's used for extruding the Belt, Tube, PCPO and granulation .

Conical Twin-screw platform is consist of the Drive device, Feeding device, Barrel ,Twin-screw and Dies parts, etc. The Twin-screw is the heart of the extruder, divided into the charging section (solid conveying zone), compression section(melting zone) and the homogenization section (the melt conveying zone) three parts. Put the material into the hopper ,under the action of a rotating screw, material was pushed on to the direction of the nose. Material endures strong shear, mixing and calendaring in the barrel, In this process, Meanwhile, the physical states of material the evolve from glass state to the high elastic state ,eventually become sticky flow pattern .
 

1. Drive device

It is mainly used to complete the plastic plasticizing and transportation by uniform rotation for torque setting, Servo motor control screw torque, pre-set torque from touch-screen.

   2. Feeding device

Conical Twin-screw platform adopts screw metering feeding device. According to the properties of material production and processing technology conditions, adjust the volume of feed speed and extrusion in order to achieve the balance.

 3,Screw

Because of its rotation, the powder or particle shape plastic was pushed to the former, so as to achieve compaction, melting and mixing purpose of homogenization.
