A process for surface cleaning or finishing metals using an air blast to impact abrasive or steel shot particles against the surface to be cleaned of scale, oxides or rust.
The cleaning and roughing of a surface by the use of sand, artificial grit or fine metal shot, which is projected at a surface by compressed air or mechanical means. See SSPC.
The cleaning process using loose abrasive propelled at a high velocity, and aimed at the area to be cleaned. This process is typically used to remove rust, scale, old paint, or any other dry surface contaminants.
Removal of sand or oxide scale from castings by the impinging action of sand, metal shot, or grit projected under air, water, or centrifugal pressure.
