Abstract
Apparatus for blending particulate solids or liquids includes a blending vessel having a racetrack-shaped cross section at each elevation above its lower end. The racetrack-shaped cross section consists of two spaced opposed semicircles having ends that are joined by two spaced parallel line segments. Several embodiments of the apparatus are described; they all employ the racetrack-shaped blending vessel, which is highly effective in promoting mixing. In one embodiment the racetrack-shaped blending vessel is rotated about a horizontal axis so that the material passes through the vessel on each revolution. In another embodiment, a number of racetrack-shaped blending vessels are connected in a vertical sequence so that the material must pass through the blending vessels in succession.
Claims6
A blending apparatus comprising:
- blending vessel having an axis of symmetry and at all points along the axis of symmetry having a racetrack-shaped cross section in a plane perpendicular to the axis of symmetry, said racetrack-shaped cross section consisting of two opposed semicircles, spaced, and with their concave sides facing each other, the ends of the semicircles joined by parallel straight line segments, said blending vessel extending downward from an upper end to a lower end;
- and
- means for rotating said blending vessel about an approximately horizontal axis, the rotating means operably attached to said blending vessel, wherein the major axis of the racetrack-shaped cross sections of said blending vessel is oriented in a different direction from the direction of said approximately horizontal axis about which said blending vessel is rotated.
