Mixing and kneading machine for continuous preparation processes, method for carrying out continuous preparation processes with a mixing and kneading machine, and use thereof

摘要

The machine has a screw shaft (3) rotating in a casing and simultaneously moving axially and translationally. The screw shaft executes reciprocation for revolutions. The screw shaft has a set of radial screw vanes (4a-4d) evenly and circumferentially distributed in a conveying direction. Each screw vane is in axial sequence, where a ratio of processing space length and outer diameter (Da) of the screw shaft ranges from 8 to 12. A processing space is formed by an infeed zone. Kneader pins protrude into the processing space. An independent claim is also included for a method for implementing continual compounding by a mixing and kneading machine.
