Used Coperion Werner & Pfleiderer ZSK 30-W9/2 Twin Screw Extruder – High-Speed Lab & Production Compounding System

Manufacturer: Coperion Werner & Pfleiderer
Model: ZSK 30-W9/2
Type: Twin Screw Extruder (Co-Rotating)
Condition: Used

Description

Used Coperion Werner & Pfleiderer ZSK 30-W9/2 Twin Screw Extruder, a compact, high-performance co-rotating twin screw system ideal for precision compounding, R&D, and small-scale production. Featuring 30 mm diameter screws and an extended 33.3:1 L/D ratio, this machine provides excellent mixing, dispersion, and process control.

The extruder includes 8 barrel sections (7 electrically heated and water-cooled) for accurate thermal management across processing zones. Powered by a 10.4 kW AC motor with gearbox, the system delivers high-speed operation up to 500 RPM, making it suitable for advanced formulations and high-shear applications.

Previously used in compounding, this unit is frame mounted and includes a control panel, offering a complete, ready-to-run solution for polymer processing environments.
