Abstract:
A rotary disc fluid mixing apparatus for mixing fluid materials in a container, comprising:support member adapted for association with said container;a mixing rotor mounted on said support member for positioning in said container, said rotor comprising an elongated shaft mounted for rotation on said support member and at least a first disc pack of a plurality of circular discs mounted on said shaft for rotation therewith, the at least first disc pack consisting essentially of a first disc having a central hub for mounting said disc pack on said shaft, a second disc having an unobstructed aperture in a center thereof, and a plurality of pins connecting said second disc to said first disc, the discs each having a substantially uniform thickness, the pins disposed at an innermost diameter defined by said aperture, the pins connecting said first and second discs in axially spaced relation at a distance less than the radius of said aperture for enabling a liquid to flow through said aperture and outward between said discs, the discs having opposed planar surfaces operative to propel the liquid by surface friction outward from the space between the discs.
