Shot Blasting is a process which smooth a surface with the help of high-velocity steel abrasive material. The shotblaster method helps in obtaining the cleaning and preparation of the surfaces for the secondary finishing operations. The selection process of the type of shotblasting equipment and Rotary Barrel Type Machine depends on the size and shape of the equipment. The surface to be cleaned, the require final surface finish specification and the overall required process. The shot blast production lines (both manual and automated systems), only became possible after the introduction of the centrifugal wheel blast machines. The system of shot blasting room with the centrifugal wheel has proven to be more productive than by compressed air and achieves a better and more uniform finishing of the surface.
In shotblasting – Throwing the shot blast media at a high speed of 65 to 110 m/second in a highly controlled way. It removed the contaminates on the surface with the help of the abrasive impact. The process of shot blasting is at its peak. It utilize air compressors for propelling the shot blast media. This method remains to clean metal frames.
