Abstract
A single screw extruder for processing thermoplastic masses has a cylinder which receives a screw, a feed opening for the material to be processed at a first end of the cylinder, an ejection zone for thermoplasticised mass at a second end of the cylinder and accessories for treating the thermoplasticised mass. A homogenisation chamber (244) designed at or after the second end of the cylinder has an outlet (268) at its downstream end away from the screw. A homogenisation rotor (246) secured to the downstream end of the screw so as to rotate therewith is arranged in the homogenisation chamber (244).
