摘要： This invention relates to a nozzle and a nozzle mix gunning system incorporating the nozzle for pneumatically propelling dry or wetted particulate gunning material toward a substrate a distance removed from the nozzle and at an angle to the line of sight of the operator. The nozzle comprises a plurality of substantially straight tubular sections. Each section is lined with an abrasion resistant material, and joined to the other sections in a manner that produces a curvature in the nozzle. The cross-section of the jacket sections and the bore of the abrasion resistant liner may be independently circular or polygonal, where a jacket or liner having a polygonal cross-section has at least three substantially flat sides.
