The ZD 9 FB twin screw feeder with flat bottom is suitable for precise volumetric or gravimetric feeding of poorly flowing and free-flowing powder, which tends to clump or cake on the hopper wall, or which has a strong tendency to form bridges. The bottom scraper discharges the bulk material gently and completely.
