The Categories of Twin Screw Extruder

According to the direction of the rotation of the twin screws, extruders can be divided into two types: parallel co-rotating twin screw extruder and parallel counter-rotating twin screw extruder. The parallel co-rotating twin screw extruder means that the two screws of the extruder rotate to the same direction but the screws of the parallel counter-rotating twin screw extruder work in the opposite directions.

According to the axis lead of the twin screw extruder parallel or not, extruders can be divided into axis lead and intersecting twin screw extruder. The parallel axis lead is the twin screw extruder, while the intersecting is the conical twin screw extruder.

Twin screw extruder can also be divided into the meshing and non-meshing.
