The twin screw extruders are 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. Maintenance costs are reduced as only worn parts need replacement.
The modular principle of the barrel permits precise sequencing for each application. Each barrel section's temperature can be set separately. Electrical heaters provide heating, and cooling is obtained with water. Barrels and elements are made out of nitride steel or wear-resistant materials for standard and specialized requirements.
Selectable order of screw elements assures mating with process configurations. Different process zones can be set up for Conveying, Kneading, Mixing, Shearing, Homogenizing, Degassing, and Pressure building.
The barrel can be opened in minutes. This makes product changeover, maintenance, and research fast and easy.
