Small-scale twin-screw feeder for powder handling

Perfect for precision in lab environments, this small-scale feeder efficiently handles challenging powders that clump or bridge, ensuring consistent flow and accurate dosing in your formulations.

Feeds and Meters Powders Precisely

The ZD 5 FB from Three-Tec GmbH is a compact, flat-bottom twin-screw feeder designed to address the challenges of handling poorly flowing and free-flowing powders. Its stepper motor-driven mechanism ensures precise metering and consistent flow, making it ideal for pharmaceutical excipients, dietary supplements, and fine chemical mixtures. Operating with a throughput range of 0.003 to 1.45 liters per hour, this feeder caters to manual, bench-top, and high-speed operations. The ZD 5 FB integrates seamlessly into laboratory and production settings, offering a small footprint solution with a hopper volume of 0.1 liters. Compliance with industry standards ensures suitability for pharmaceutical, chemical, and food applications. Configurable settings and support for gravimetric systems enhance its versatility in demanding environments.
