ABSTRACT:
A mixing device of the type having a housing of generally cylindrical construction, having an end wall with concentric arrays of axially extending mixing elements thereon, a rotor being rotatable within the housing and having on the face thereof further axially extending mixing elements in a plurality of annular concentric arrays, the mixing elements of the rotor and housing interfitting with one another. The mixing elements themselves are each defined by inner and outer part-cylindrical surfaces and by further straight surfaces forming the sides of grooves, the axes of the grooves being disposed along different tangents to an inner pitch circle which is concentric with the part-cylindrical surfaces. This provides a much better mixing effect and produces a certain reverse pumping within the mixer. These features enable the mixing elements to be made shorter with the possibility of the rotors and end walls of the housing being formed by moulding.
