Leistritz Has a Dual Purpose
American Leistritz Extruder Corp., headquartered in Somerville, N.J., has introduced its “dual-purpose” twin-screw extruder system for use in wide ranging color and related dispersive mixing applications.

The system includes either a ZSE-18, ZSE-27 or ZSE-40 mm high-speed twin-screw extruder with a screw design and process section configured for intensive mixing. A gear pump is attached to the front end to build pressure to drive the melt stream through a filtration media, typically 300 to 400 mesh screens, contained in a breaker plate assembly. The Leistritz Macromatex TSCS™ PC based control package allows the pressure in front of the screen pack to be tracked in a defined and repeatable way, with the results available and achieved in both spreadsheet and graphical formats. Both master batch and letdowns can be tested.

When not utilized for pressure rise testing, the twin-screw extruder can be mated with a downstream palletizing system for concentrate compounding development, just like any twin-screw extruder. Pelletizing systems typically do not use the gear pump attachment, unless very fine filtration is required; a gear pump is more commonly integrated with sheet/film/profile/fiber applications. All of these products can be extruded with the dual-purpose, twin-screw extruder system.
