Spare Parts for Co-rotating Parallel Twin Screw Extruder
1. Descriptions
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.

Screw elements with various pitches and lengths
Kneading blocks with various angles of stagger, numbers of kneading disks and disk widths
Screw tips to fix the screw set axially
Gear teeth connection to ensure power flow between the screw shaft and screw elements.
