摘要

A method of mixing viscous fluids is disclosed. The method comprises rotating a mixing apparatus ( 20 ) in a container ( 42 ) of fluid ( 44 ). The mixing apparatus comprises a cage ( 21 ) located at the end of the shaft ( 22 ). The cage ( 21 ) comprises a central circular disc ( 24 ) with an outer edge ( 43 ) and top ( 38 ) and bottom ( 40 ) sides. A number of vanes ( 26 ) extending from each side of the disc ( 24 ), the vanes ( 26 ) spacedly located near the outer edge of the plate. The free ends of the vanes ( 26 ) are connected by a hoop ( 38,40 ) to maintain their spaced relationship.
