High-volume wet blast machines clean, descale, degrease surfaces in single operation

May 16, 2011

Rosler's KS series wet blast machines come in standard machine cabinet sizes from 28 to 60 in. square with a variety of sump and media capacities. According to the manufacturer, the machines provide uniform media flow and high finish control.

The high-volume, self-contained machine uses a slurry of abrasive media and water to clean, descale, and degrease surfaces in a single operation. The slurry is directed through a 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 it is closed-loop, with the media and water recirculated, there is no need for a drain. It also eliminates wastewater pollution and disposal requirements.

The water is used as a buffer between metal and media to cushion the shock and reduce the downward force; this eliminates the surface impregnation possible in traditional media-to-part processes, the company says.
