Patent attributes
A vortexer apparatus including a vessel comprising an exterior surface, an interior surface and a mouth for receiving material at an upper end of the interior surface. An outlet passageway extends downwardly from the interior surface. An inlet opening is located between the interior and exterior surfaces above the outlet passageway. The inlet opening is offset from the center line of the interior surface. A pump is adapted to pump fluid into the vessel to form a vortex in the vessel. The base and impeller of the pump are configured and arranged effective to provide molten metal leaving the base with a positive pressure. An outlet conduit extends from the base outlet to near the vessel inlet opening and can be maintained at a temperature above which molten metal solidifies, along it's entire length.
