Flat-bottom twin-screw feeder for precise powder feeding
When dealing with both poorly flowing and free-flowing powders, accurate volumetric or gravimetric feeding is a critical challenge. Ensuring a consistent feed rate without clogging or irregular flow can complicate the process, especially in pharmaceutical and other high-precision applications.
Achieve precise and consistent powder feeding
The ZD 22 FB flat-bottom twin-screw feeder by Three-Tec is engineered for high precision in feeding poorly flowing and free-flowing powders. Its design includes a bottom scraper and mesh guard, ensuring smooth material handling. Constructed from full-stainless steel and polished to a ground finish (Ra 0.8/Ra 0.4 µm), it promises durability and ease of cleaning. The feeder operates in both volumetric and gravimetric modes, with a feeding rate ranging from 2.1 to 420 liters per hour.
