Abstract

A mixing machine has a mixing chamber in which there are disposed at least two rotors arranged for rotation in opposite directions about respective rotational axes. The rotors have a helical projection and are rotatable so as to present a leading face of the projection to the material being mixed. The leading face has a discontinuous profile along the axial direction of the rotor so as to define first and second portions. A majority of the leading face (17) of the first portion (12) is concave and a majority of the leading face (19) of the second portion (13) is convex. The circumferential length of a tip (W1, W2) surface of the projection increases in the axial length of the rotor. A clearance defined between the tip of the projection and a facing wall of the mixing chamber decreases in size in the direction of rotation of the rotor. The rotor profiles are designed to provide zones which act on a material to be mixed in different ways so as to improve overall mixing quality and efficiency.
