Abstract: A mixer for producing a substance mixture includes a rotatable shaft and a body submersible within a first substance. The body includes a first end and a second end. The first end is coupled to the shaft, and the second end includes an outwardly flared opening. The mixer also includes a plurality of apertures disposed on a wall of the body. Rotation of the body draws the first substance and a second substance into an internal area of the body and dispels the substance mixture outwardly through the apertures. The mixer may also include a diverter for diverting the substance mixture toward the apertures. The mixer may further include internally formed vanes to increase a substance flow rate into the mixer. Screens may also be disposed outwardly from the apertures to enhance mixing of the first and second substances.
