Abstract
A blast head for abrasive blasting has a nozzle for directing a blast media at a surface being treated and a housing for containing the blast media after it passes through the nozzle and for facilitating recirculation of the blast media. An adjustment mechanism facilitates varying of the orientation of the nozzle with respect to the surface being treated, so as to facilitate enhanced blasting thereof.
