Shot Blasting Machine
Shot Blasting Machine is used as a mechanical method for the surface treatment by using an abrasive with the help of a centrifugal wheel at high speed to obtain excellent surface and remove impurities for secondary operations. Shot blasting is done in two ways: Wheel blasting: It is a common and economical method. In this process, the electric motor energy is converted into kinetic energy by rotating a turbine wheel. This is mostly used for treating heavy equipment. The turbine wheel works here as a centrifugal pump and it delivers the abrasive by centrifugal force on the surface. Air blasting: In this method compressed is used and sprayed out through nozzles on the surface. This is mostly used for smaller equipment. Air blasting is comparatively expensive due to the use of steel frames and weldments. After the process of shot blasting, shots are removed by the air washing process. The shot blasting machine works on the projectile motion of an abrasi...
