Features:
The XINDA PSHJ twin screw series are built on a modular system. The major advantage of this modular design is the versatile configurations. Processing tasks can be optimally accomplished with only a few barrel and screw variations.
Clam shell Barrel
The barrel can be opened in minutes. This makes product changeover, maintenance and research fast and easy.
Barrel Section- Separately controlled
The modular principle of the barrel permits precise sequencing for each application. Each barrel section's temperature can be set separately. Electrical heater shells provide for heating, cooling is obtained with water. Barrels, as well as screw and kneading elements are made out of nitrided steel in the standard version, the wear resistant version is made of suitable materials, corresponding to the respective requirements.
Standard barrels
The freely selectable order of screws and kneading elements assure the process sections mating the process configuration. Thus, different process zones can be set up interchangeably, according to the requirements for: Conveying;Plasticizing;Mixing and shearing;Homogenizing;Degassing;Pressure building
The procedural steps in compounding are:
1.Metering
2.Feed intake and conveying
3.Melting
4.Dispersion/Homogenizing
5.Degassing
6.Pressurization
7.Screening
8.Pelletizing or producing semi-finished products
The classic areas of application of PSHJ twin screw extruder are:
1.The mixing and dispersion of additives and pigments
2.Reinforcing
3.Filling
4.Treatment of temperature and shear sentitive products, e.g., PVC, XLPE, etc
5.The degassing of volatile components
