Gerneral Characture of XINDA's Plastic Mini labtech Testing Twin Screw Extruder Polypropylene Granules Machine
Modular construction
XINDA's twin screw extruder/Plastic Extruder are built on a modular system. Screw elements with different length and function
are mounted to the main splined shaft. The screw combination are changeable. Thus, with a few screw elements and barrel
variation, different processing tasks can be finished on the same machine. Besides,when part of screw element,liner or barrel
wear out, we only need to replace the broken parts instead of replacing the whole screw or barrel. Maintenance cost saves!
Temperature Separately controlled
The modular principle of the barrel permits precise sequencing for each application. Each barrel section's temperature can be
set separately. Normally,electrical heaters provide 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.
Standard barrels
The freely selectable order of screw elements assure the process sections mating the process configuration. Thus, different
process zones can be set up interchangeably, according to the requirements for: Conveying;Kneading; Mixing and shearing;
Homogenizing; Degassing; Pressure building.
