Abstract
An improved particle blasting apparatus for continuously monitoring media flow, nozzle wear, and nozzle blockage. The apparatus includes a source of compressed air, a nozzle, structure for conveying the compressed air from the source to the nozzle in an airstream, structure for introducing the media into the airstream to be carried by the airstream, and an air flow rate meter in the air conveying structure to indicate the air flow rate therein. In a preferred embodiment, indicator lights are included which are illuminated if the air flow rate falls outside of an acceptable range. A method of using the particle blasting apparatus is also disclosed.
