Abstract
Apparatus for mixing a material contained in a vessel comprises one or more flow channels and at least one pair of first and second members which are coaxially mounted one within the other about an axis of rotation such that their facing surfaces curve around the axis defining a chamber therebetween. At least one of the first and second members having a non-circular curvature, the first and second members being rotatable relative to one another about the axis to thereby produce a pumping force to force material through said flow channels. The radially outermost of said first and second members moves to a wall of the vessel relative to stress and displace material present between the mixing apparatus and the wall of the vessel.

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.
