Rosler’s KS series wet blast machines use a high-volume slurry of abrasive media and water to clean, descale and degrease surfaces in a single operation. The slurry is directed through a special high-volume, internally-mounted pump to a blast gun where regulated air pressure adjusts the aggressiveness of the process. The process is free of dust and chemicals, and because the media and water are re-circulated, there is no need for a drain, the company says. This closed-loop system also eliminates wastewater pollution and costly disposal methods.
In addition, by using water as a buffer between metal and media to cushion the shock and reduce the downward force, the wet blasting machines also are said to eliminate the surface impregnation possible in traditional media-to-part processes. The machines are suited for cleaning and deburring molds, circuit boards, parts and castings as well as preparing high-performance surfaces for etching, matte finishing, peening and texturing. Cabinet sizes range from 28 to 60 sq in, and a variety of sump and media capacities are available.
