Abstract
The useful life of a dry abrasive blasting head is greatly extended by two design features. First, the tube on which the rotating nozzles are mounted is protected from abrasion by an easily-replaced wear tube which is a sleeve-like liner. Secondly, the relatively expensive nozzle holder is protected by providing it with a cup-shaped cavity facing the incoming abrasive particles. The cup-shaped cavity soon becomes at least partially filled by the particles, so that later-arriving particles strike the particles contained in the cavity and do not directly reach the nozzle holder, thereby prolonging its life. Taken together, these structural features of the present invention result in a high-performance blasting head that can operate for more than 1,000 hours without interruption.
