Extrusion Conical Twin Screw Barrel
Twin screw extrusion
Simply described, the twin-screw extruder is a machine consisting of two co-penetrating and self-cleaning identical screws which are mounted on shafts and rotate in the same direction in a fixed closed housing called [barrel" . The twin-screw extruders operate continuously with very short residence times.
The parallel twin screw and the conical twin screw
According to whether the screw axis is parallel or not, the twin screws can be divided into the conical twin screw and the parallel twin screw, where the parallel twin screws are divided into fully intermeshing type, partly intermeshing type, non-engaged type, etc. In the case of parallel screws, the feed end and the die end have the same diameter.
The diameter of the screws in the conical twin-screw extruder is larger at the feed end and smaller at the die end.
