ABSTRACT:
A particulate spray nozzle is disclosed having an internal mixing chamber with a liquid spray orifice on one side and a liquid and particulate discharge bore opening the opposite side to ambience. A liquid supply passage upstream of the orifice contains a disc-like diffuser with the plane of the disc parallel to and aligned with the longitudinal axis of the orifice. The diffuser is spaced axially from the orifice and the orifice is spaced axially from the discharge bore for causing a high pressure liquid to be discharged from the orifice in the form of a narrow gradually diverging spray which picks up particulate material in the mixing chamber and propels it out of the discharge bore by uniformly engaging only the outer most portion of the discharge bore. The apparatus can function as an abrasive blasting assembly or a chemical foaming gun. A method of discharging particulate materials, which may be either solid or liquid, is also disclosed.
