Product Description
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.
The barrel can be opened in minutes. This makes product changeover, maintenance and research fast and easy.
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 nitride steel in the standard version; the wear resistant version is made of suitable materials, corresponding to the respective requirements.
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.
