Abstract
A mixing blade assembly including a hub, a set of impeller blades having air foil configurations and flat end portions for attachment to corresponding flat surfaces of mounting members which attach the blades to the hub. The flat attachment surfaces avoid stresses tending to distort the blades. The hub is a hollow member made from a set of plates. The leading edges of the blades are generally straight, and the trailing edges are inclined rearwardly from the tips towards the roots of the blades.
