ABSTRACT:
A mixing nozzle for producing a high velocity jet of airborne abrasive slurry comprising a cylindrical air passage of a length at least 2.5 times its diameter, a concentric circular chamber surrounding the cylindrical air passage and having a tangential entry for the abrasive slurry, and a nozzle portion having a region tapering from the diameter of the concentric circular chamber to a cylindrical region. The diameter of the cylindrical region should have a diameter lying between 1.2 and 3.0 times that of the air passage and a length at least six times its diameter. The air passage and the concentric chamber with its tangential entry is preferably formed as a replacement insert made from a wear resistant material.
