ABSTRACT:
To reduce dust and improve the productivity of wet blasting, a blast nozzle and a method of using same are provided for directing a stream of abrasive particles entrained in compressed air to a targeted surface and for injecting a pressurized water stream into the stream of abrasive particles at a point downstream of the orifice of the blast nozzle and in the expansion portion of the nozzle. At the injection point, the velocity of the entrained abrasive particles is substantially equivalent to the velocity of the injected water stream.
