Xtruder™ Radial Extruder

Production scale twin screw extruder with screens are capable of producing 0.5mm to 2.0mm diameter extrudates. The Xtruder can be provided with a cooling option for temperature sensitive material and has a bypass feature that allows for pressure relief.

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.
