SURFACE APPLIED ABRASIVE CLEANING APPARATUS AND METHOD

摘要

A rotor assembly is provided for blast processing. The rotor assembly includes multiple lofting elements to create a vortex to loft particulate material to be used to process a target, and multiple impelling elements to project the particulate material toward the target. The rotor assembly is enclosed within an operating chamber that has a target area into which the particulate material is projected to strike the target. There may further be angled deflectors at the opening to direct particulate material back toward the rotor assembly to use the material for further processing. Certain components are easily adjustable for different sizes and shapes of target. The action of the rotor assembly enables the use of up to 100% pure grit for entire cleaning processes, and provides single pass hook profile on any common material surface.
