ABSTRACT:
A method and apparatus for shot blast cleaning a workpiece. The method comprising the steps of applying a composite stream of a slurry consisting of carrier liquid and particulate abrasive material under high velocity to the workpiece in a blast cabinet, reclaiming spent slurry after undersized abrasive material have been removed, cleaning the carrier liquid for reuse and pumping the cleaned carrier liquid at the workpiece for washing and conditioning the workpiece or pumping the cleaned carrier liquid together with the reclaimed abrasive material as a composite stream at the workpiece. A nozzle which has a divider within it for separating the abrasive material and carrier liquid is used in combination with a slurry discharge head to discharge the abrasive material and carrier liquid in a substantially overlapping blast pattern.
