The Main Feature of Counter-rotating Twin Screw Extruder

The vertical flow channel of counter-rotating twin screw extruder is closed due to its geometric parameters, so materials are forced to move towards screw conveyor, which is the so-called positive displacement. This makes the stability of forming extrusion become the main feature of counter-rotating twin screw extruder. On the twin screw extruder, therefore, it should be specified in the direction of rotation.
