Abstract:
Apparatus for mixing a material, comprising a mixing head and a mixing vessel, the mixing head comprising at least one pair of first and second members which are coaxially mounted one within the other about an axis of rotation with the first member disposed within the second member such that facing surfaces of said first and said second members curve around said axis defining a chamber therebetween, and one or more flow channels communicating with said chamber, at least said second member having a non-circular curvature, said first and said second members being rotatable relative to one another about said axis to thereby produce a pumping force to force material through said one or more flow channels and said chamber, wherein the vessel has a substantially circular inner wall and said second member and said inner wall are rotatable relative to one another to stress and displace material present between said mixing head and the wall of the vessel.
