Abstract

See full text

An internal mixer includes a mixing chamber enclosed by a housing, a feeding neck in which a ram is guided, a closable discharge door, and an intermeshing rotor system, composed of a pair of rotors that can each be rotated about a rotor longitudinal axis, each rotor comprising a rotor main body on which at least one respective rotor blade is arranged, and the rotor blades of the two rotors meshing with one another, is to be refined in such a way that an improved, that is, faster, pull-in behavior is achieved, while optimizing the dispersion and distribution of the introduced materials. To this end, it is provided that in the case of at least one of the rotors, the rotor main body, at least in sub-regions, is non-cylindrical and has a non-circular cross-section, in the surface sections in which no rotor blades are arranged on the rotor main body.
