Shot blasting machines are a type of machine used for cleaning and preparing surfaces for further processing. These machines are commonly used for shot peening, which is a process that increases the fatigue life of parts and components by compressing and hardening the surface. Shot blasting machines are used to clean and prepare surfaces for painting or other coating applications, as well as for removing rust, scale, and other contaminants from a variety of metals and other materials.

The process of shot blasting involves the use of a high-velocity stream of abrasive particles to remove surface contaminants and improve the surface finish of a material. Shot blasting machines use steel shot, which is made up of small, round particles of steel, as the abrasive material. The steel shot is propelled through a hose or nozzle at a high velocity, typically between 20 and 40 meters per second, to impact the surface of the material. The particle of steel shots then rebound off the surface, removing contamination, rust, scale, and other contaminants.

Steel shots size

The size of the steel shot used in shot blasting machines is an important factor, as it affects the effectiveness of the process. The size of the steel shot is typically measured in mesh size, which is determined by the number of openings in a 1-inch square screen. 

The mesh size of the steel shot used for shot blasting can range from 12 to 500, with 12 being the coarsest and 500 being the finest. Generally, the larger the mesh size, the finer the steel shot and the more effective the cleaning process.

Shot blasting machines can be used to clean a wide variety of materials, including metals, plastics, ceramics, and composites. 

Type of steel shot 

The type of steel shot used in a shot blasting machine should be selected based on the material being cleaned and the desired outcome of the process. For example, softer materials such as plastics and composites may require a finer mesh steel shot while harder materials such as metals may require a coarser mesh size.

In addition to the size of the steel shot, the hardness of the steel shots also affects the effectiveness of the shot blasting process. Steel shots are available in a variety of hardness levels, ranging from soft to hard. Generally, softer steel shots are used on softer materials, while harder steel shots are used on harder materials. Read more: - Steel shot suppliers

Conclusion

Shot blasting machines are an effective and efficient way to clean and prepare surfaces for further processing. Selecting the right type and size of steel shot for a shot blasting machine is an important factor in achieving the desired outcome of the process. The size and hardness of the steel shot should be selected based on the material being cleaned and the desired outcome of the process.
