Operation

The wet mix, which is typically prepared in a kneader, pug mixer or high shear granulator (pharma), is metered into the feed hopper by a feeder or hand fed. Twin screws transport material into the extrusion zone where tapered extrusion blades wipe material through perforated screens creating cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step.
