  • Apparatus for separating abrasive blasting media from debris
    Patent number: 6514128
    Abstract: An apparatus for recovering and cleaning contaminated abrasive blast media. A transportation assembly supplies contaminated blast media to an in feed cylinder within a rotating drum separator. The drum separator is formed from a plurality of elongated spaced parallel-aligned elements that define gradation openings between adjacent elements. The blast media is transported within the drum along the gradation interior surface. An internal spiral vein on the inside of the drum surface moves the media progressively through the drums exposing it to different areas of the drum surface having different gradation configurations. An air wash separator receives filtered blast media from the drum for final separation processing and reuse.
