Abstract

Appts. for mixing and homogenising plastic materials has at least one profiled rotor with at least two teethed rings spaced axially from each other, and having teeth of different heights, the material forced inside the housing by the endless screw passing between the teeth of the rotor. Efficient mixing and homogenisation and easily manfd rotors.
