Abstract: The present invention embodies a spray nozzle for mixing and spraying a mixture of liquid and dry material. The device is comprised of a liquid injector, a torpedo, a spray tip, and a mixing chamber. The mixing chamber is connected to a hose that directs dry material through the apparatus. Dry material is forced around and over the first end of the torpedo within the mixing chamber, slowing the speed of that material and focusing it toward the second end of the torpedo where it mixes with liquid exiting the spray tip at this second end. The torpedo blends the dry and liquid components more uniformly resulting in a more homogenous material.
