Abstract
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.
Claims10
A nozzle comprising a plurality of tubular sections, each section having an inner surface with an abrasion resistant material adjacent thereto for protecting the surface against abrasion and at least one end portion which is angled, said abrasion resistant material forming an internal bore which is substantially straight in each tubular section, and means for joining the sections together to produce an angle of curvature in the nozzle of between about 25.degree. and 90.degree..
