Volumetric single-screw feeder for fine dosing
Achieve precise and consistent dosing of fine powders and granules with a compact, volumetric single-screw feeder, designed for seamless integration into bench-top operations and manual processes.

Dispenses Powders and Granulates with Precision
The ED 12 from Three-Tec is a volumetric single-screw feeder designed for precision dosing of small, free-flowing particles such as powders, flakes, and granulates. This feeder excels in applications requiring fine dosing, commonly used in the pharmaceuticals, fine chemicals, and food industries. It supports both horizontal and vertical discharge, addressing different spatial setups within a line. With a capacity of 2.4 to 35 liters per hour, depending on the motor type, it is adaptable for varying production needs.
Specialized for bench-top operations, the ED 12 is well-suited for laboratory and small-scale production environments. It features a streamlined design without a bridge breaker, ideal for products with particle sizes up to 2 mm. The system is reliable and easy to integrate, making it perfect for manual operations. Available with either an AC three-phase motor or a stepper motor, it provides flexibility in operation speeds, aiding in precise control over process requirements. Additionally, its compact build allows seamless incorporation into existing setups, ensuring efficient process management without extensive modifications.
