Description

Used Leistritz ZSE 18 PH-40D twin screw extruder system, designed for laboratory, pilot-scale, and pharmaceutical processing applications. This compact, high-performance extruder features co-rotating 18 mm twin screws with a 40:1 L/D ratio, delivering excellent mixing, dispersion, and process flexibility.

The system includes 8 barrel sections with (7) heated zones, utilizing electrical heating and water cooling for precise thermal control. Powered by a 4.7 kW (6.3 HP) AC drive motor, the unit can operate at speeds up to 600 RPM, making it ideal for small-scale production and R&D applications.

Mounted on wheels for mobility, this system is easy to position within lab or pilot environments. The package includes a complete downstream setup:

• Product loader

• K-Tron dosing station for accurate feeding

• String die

• Pelletizer for material finishing

• (3) temperature controllers

• Spare parts package

Previously used in a pharmaceutical environment, this system is well suited for regulated applications requiring precision and repeatability.
