An Extruder Granulator is a mechanical granulation system that converts wet powder mass into uniform cylindrical granules through controlled extrusion. The material is fed into a screw or die-based extrusion chamber where pressure forces the mass through perforated screens or dies, forming consistent extrudates that can be cut to the desired length. The system provides precise control over granule diameter, density, and shape, making it suitable for continuous and high-throughput granulation processes.
