Sandblaster

A sandblaster is a machine that uses abrasive materials with air pressure to clean or prepare surfaces for painting or other coatings. Also used for shot peening to remove stress from metal products that have been cast or forged or formed and in some cases welded. Abrasive media is put in a tank and air pressure to the same pressure you would be blasting. The media is then by gravity dropped into a blast hose line which will push it out of a blast nozzle at what ever the air pressure you are using. Sandblasting machines are used in many industrial areas and even crafts. Glass is frosted with a sand blast machine. Usually for design or art work.
