ABSTRACT:
An improved nozzle for a gun or output means of a particle blast apparatus such as a sand blast cleaning device. The nozzle has a wear indicating lip that clearly and unambiguously shows the operator when the nozzle has reached the end of its useful life and should be replaced. The nozzle is elongated and tapered to improve power and accuracy. The nozzle has a proximal media inlet end which has a predetermined configuration which maximizes media/air mixing and flow, and minimizes turbulence and nozzle/gun interface wear. The invention also provides a method of using a particle blast apparatus, and particularly for determining when a nozzle has worn and should be replaced.
