ABSTRACT:
A device for mixing liquids, solids or combinations thereof, particularly viscous liquids and polymeric solids comprises a mixing vessel having therein a substantially cylindrical mixing chamber; a rotor with a cross-section in the shape of a convex-convex lens having outer convex surfaces substantially identical in shape to the inner wall surface of the cylindrical mixing chamber and with a longitudinal dimension substantially identical to that of said cylindrical mixing chamber, the rotor being variably positionable so it's rotating axis is parallel to the axis of the mixing chamber, but eccentric thereto, and mounted within the mixing chamber upon a base having a drive mechanism for the rotor disposed through it; and a lid for tightly sealing the chamber formed by the mixing vessel and the base. The rotor preferably fills from 28 to 100% of the volume of the mixing chamber; most preferably 50 to 75%. The rotor may be heliciform along its longitudinal axis.
