ABRASIVE BLASTING

Garnet granules are also used in abrasive blasting (commonly known as “sand blasting”). In these processes, a tool propels a stream of abrasive granules (also known as “media”) against a surface using a highly pressurized fluid (usually air or water) as a propellant. Abrasive blasting is done in order to smooth, clean, or remove oxidation products from metals,brick, stone, and other materials. It is usually much faster than sanding by hand or with a sanding machine. It can clean small and intricate surfaces that other cleaning methods would miss. Abrasives of various harnesses can be used to clean a surface of greater hardness, without damaging the surface.
