Abstract

PURPOSE: To eliminate irregurarity of working and utilize efficiently energy of high pressure water jet by supplying abrasives to both surfaces of high pressure fluid jet injected in blast working to project the abrasives to materials to be processed with high speed.
CONSTITUTION: High pressure water is injected from a nozzle 2 of a high pressure water header 1 to a horizontal surface to be processed of a material 3 slantly from above in the form of flat spray pattern. Abrasives 6, 8 are supplied from first and second supply pipes 5, 7 to the upper and lower surfaces of the high pressure water jet 4 to mix the abrasives 6, 8 throughout the upper and lower surfaces of the jet 4. By this mixing, kinetic energy of the high pressure jet is efficiently converted into blasting energy and the abrasives 6, 8 are accelerated with high speed to be projected to the surface to be processed without irregularity of work for blast working.
