Grit Blasting Machines
Grit blasting machines use abrasive materials like sand (in the case of sandblast equipment) to remove contaminants from the surface of parts. This is accomplished by spraying the parts with abrasive materials at very high pressures to remove dirt, rust, and other buildup. The result is a cleaner, stronger part that can be restored to work or look as it was originally intended. Grit blasting machines are particularly helpful in the automotive restoration industry, where they are used to clean parts after a car has been disassembled. Once the parts have been blasted, they can be painted, and the car can be restored to its original appearance. Unlike when a part is sanded manually, a grit blaster will get into every crack and crevice because the particles of most abrasive materials are so small. This process results in a more thorough and effective cleaning and surface finish.

Types of Grit Blasting Machines
There are many types of grit blasting machines and each one is optimal for a particular industrial or commercial application. A grit blasting cabinet is used in shop applications where parts need to be treated without creating dust in the surrounding area. The part is inserted into the cabinet, which is then sealed before the pressurized abrasive material is forced through nozzles into the chamber. The operator can turn the machine on and off using a foot pedal, and rubber glove hand inserts allow them to pick the object up and move it around as it is being blasted. A blasting room works in much the same way as a blasting cabinet, except it is much larger, and the operator actually works inside the room while wearing heavy protective equipment. Other types of grit blasting machines use hydro-blasting, wheel-blasting, dry-ice blasting, and automated blasting. Hydro-blasting, for example, uses highly pressurized water to blast surfaces like the exterior walls of buildings. Dry-ice blasting uses air and dry-ice under pressure that is ejected from a nozzle. This effectively removes surface contaminants due to the force of carbon dioxide.
Things to Consider When Purchasing a Grit Blasting Machine
Grit blasting is an effective way to harness the abrasive qualities of the material to clean an industrial or commercial component thoroughly. The various styles and sizes of available grit blasting machines make abrasive blasting a perfect solution for companies in many different manufacturing and repair industries.
