According to the structure, the shot blasting machine can be classified into drum-type, chain plate type, trolley type, squirrel-cage type and rotary table type. However, the shot blasting machine accessories are quiet similar. Concretely speaking, a whole shot blasting machine system can be divided into four main parts, including impeller head, shot collecting, separation and transportation system, supporting body and dust pelletizing system. In general, the impeller head will cast the shot to certain direction under the function of high centrifugal force that is generated from the high-speed rotary vane wheel. The part that is continuous to operate and overturn is called supporting body during the cleaning process. The dust pelletizing system, just as its name implies, is used to make sure the clean operating environment.
When it comes to the function of shot blast machine, here is the brief introduction. First of all, it is widely used to clean the workpiece surface. For example, it can eliminate the burrs and rust of the iron castings. The elimination of scale cinder from various castings is also one of functions. As we all know, every single casting should be through quality inspection before leaving factory. Therefore, to a large extent, surface treatment by shot blasting machine is an indispensable step of casting production.
Besides, it also can be used to remove the surface contaminants from coating and provide a surface profile that can augment the coating adhesive force, which realizes the goal of strengthening the workpiece. In the meantime, it can reduce the fatigue life of workpiece through increasing different surface stresses. In the end, the strength of workpiece can be improved largely, which is another method to strengthen the workpiece. Just because of these functions, the shot blasting machine is widely applied to such industries as aerospace, automobile, aviation and tractor. After all, they ask for light-weight but high-reliability components and parts.
