Media blasting is also known as abrasive blasting or rough blasting. In this process, fine abrasive particles containing powdered rock salt are blown against a hard surface with compressed air. It has a less harmful abrasive effect on concrete than fine sandblasting. An early application was on the preservation of the Statue of Liberty during the late 1980s. Experts carried out media blasting to remove rust, stains, and contaminants from the glass of the statue. Visit this link for more info.
For that purpose, a hard metal abrasive, such as steel wool, aluminum oxide, or graphite, is placed on the top of the iron oxide layer. When it is time for the air to be released, it shoots straight up from the nozzle. The abrasives are shot against an exterior surface, such as concrete, asphalt, or vinyl, at extremely high speeds. The strips of media that come off are usually very thick and durable. They are used to stripping away loose surface materials, like pebbles, to make way for clean rainwater drainage.
Another application for dry abrasive blasting equipment is found in the manufacture of concrete slabs. It involves the application of a thin circular abrasive that is spun around in a cylindrical media jet. The spinning action of the media helps to increase the amount of abrasiveness along the grain of the concrete, reducing the amount of solid debris that can build up on the surface. After application, it is important to allow the concrete to dry completely before walking on it.
There are several applications for paint and chemical agents that can be made through media blasting. For instance, dry paint can be made by spraying fine powder paint chips on a metal surface without disturbing the surface. In the case of soda blasting, fine aluminum oxide chips are placed on a target surface, where they quickly oxidize to produce an effective paint finish that is free of fumes and will not damage the surrounding surface.

A similar application method to paint application involves compressed air cleaning. This method does not use paint, but rather, compressed air is used to blast clean dust particles from surfaces, which is then brushed away or sprayed away. For this method to work, a blasting station is necessary, and often only one machine is used. The compressed air is released from a compressor, and the particles are blasted away or collected without damaging the surrounding area.
Wet Abrasive Blasting System involves the application of a high-speed media blasting equipment system that spins and agitates abrasive material onto a drum that is rotated at extremely high speeds. It consists of a spinning blade and rotating brushes that remove and clean away surface contaminants and create an interior layer of ultra-fine abrasive material. Abrasive media blasting equipment is typically used in large-scale and industry-related projects, such as oil explorations, geophysical surveys, the handling of contaminated chemicals, and the removal of heavy metals from soil. This cleaning method produces a highly effective finish and protects surrounding surfaces from contamination.
