Co-rotating Twin Screw Extruder
Modular construction: The twin screw extruder is built on a modular system. Screw elements with different lengths and functions are mounted to the main splined shaft. The screw combination is changeable. Thus, with a few screw elements and barrel variations, different processing tasks can be finished on the same machine.
Temperature Separately controlled: Each barrel section's temperature can be set separately. Normally, electrical heaters provide heating, and cooling is obtained with water. Barrels, as well as screw and kneading elements, are made out of nitride steel or wear-resistant materials.
Standard barrels: The order of screw elements assures process configuration for Conveying, Kneading, Mixing, Shearing, Homogenizing, Degassing, and Pressure building.
Clamshell Barrel
The barrel can be opened in minutes. This makes product changeover, maintenance, and research fast and easy.
