Abstract
A mixer impeller made up of paddle shaped blades, which near their tips (e.g., at 90% of the radius of the impeller from its axis of rotation) are of a width at least 40% of the impeller's diameter. The blades also having camber and twist. They are formed by establishing bending moments which form the blades into sections which are curved and flat, with the flat sections being at least in the center area of the base of the blades.
