Extrusion Solutions

The Stand-alone TSE 20/40 Extruder is a self-contained twin-screw extrusion system with a 12kW inverter drive. The advantage of the integrated motor, allows the system to reach a higher rotary speed (max. 1200 rpm) than a Twin-Screw Extruder powered by a drive-unit. The processing unit is a clamshell design with segmented screws. The modular screw design enables the operator to optimize the compounding application by utilizing various kneading, mixing, and shear elements of the screws. The segmented screw elements are interchangeable and can be realigned to adapt to a specific application. The TSE 20/40 is available with barrel lengths of 20 or 40 D. Metering and/or venting ports are located at 10 D, 20 D, and 30 D with side feeding capabilities (12 D and 22 D). Furthermore, the barrel of the TSE 20/40 is divided horizontally, and can be tilted open on both sides to allow visual assessment of individual processing steps.


 The Brabender® Mini-Compounder TSE 12/36 is a miniature co-rotating twin-screw extruder with application to the chemical as well as the pharmaceutical industry for development of new products.  The unit has an integrated drive with an output of 2.4 kW (3.2 HP) and reaches speeds up to max. 600 RPM. The clam shell barrel (length: 36 D) is divided horizontally and can be titled open to allow visual assessment of individual processing steps, easy mounting of the screws and quick cleaning of the barrel. The modular screw concept offers various individual processing possibilities. Even minimum samples as is especially required in the pharmaceutical industry can be processed with the Mini-Compounder. In addition to the main metering, metering or venting ports at a barrel length of 4.5 D (liquid only), 10 D and 27 D are available. Side feeding can be installed at 12 D length.
