Volumetric single-screw feeders for free-flowing products
Achieve precise and continuous feeding of free-flowing powders, flakes, and granulates with adjustable throughput options, ensuring accuracy and efficiency in your dosing processes.
Feeds and Doses Free-Flowing Materials
The ED 20 and ED 20 B feeders from Three-Tec offer precise volumetric feeding for diverse industries, including chemical, pharmaceutical, and food sectors. These single-screw feeders are engineered to handle free-flowing powders, granulates, and fibers seamlessly. Both models provide consistent dosing with throughputs ranging from 0.4 to 277 l/h, depending on the motor type. Equipped with optional bridge breakers and customizable discharge configurations, the feeders ensure uninterrupted material flow. Integration into existing lines is facilitated by horizontal or vertical discharge options, while servo motor controls enhance dosing accuracy. The feeders support varied hopper capacities and are constructed to meet industry-specific material standards, ensuring reliability and performance continuity.
