[0002] Shot blasting machine is a mechanical equipment used for metal surface treatment. It is mainly used to remove oxide layer, rust, dirt, old paint, etc. on the metal surface to improve the cleanliness and roughness of the metal surface and enhance the adhesion of the coating. Shot blasting machine is usually equipped with a shot blaster inside. The shot blaster accelerates the projectile and makes it impact the workpiece surface at high speed. Shot blasting machine has a wide range of applications in the field of metal surface treatment. It can improve the quality of metal surface and extend its service life. It is an indispensable equipment in modern industrial production.
