sandblaster

Machine-translated from the German article

A sandblasting machine () is a technical device by which an abrasive medium (sometimes sand, but today mostly other materials such as blast furnace slag, glass granules, corundum, steel, plastic granules, nutshells, soda, ice crystals, CO2 snow pellets) is blown onto objects by compressed air or a centrifugal wheel, in order to remove rust, paint, burrs or the like from them or to roughen them. The use of the device is also called sandblasting. A typical sandblasting installation (see photo, technical term "compressed-air blasting with solid abrasive") consists of a pressure vessel filled with abrasive, which is connected "laterally" to a compressed-air hose.
