Overview and working principle of shot blasting machine

Shot blasting machine is widely used in various production industries. In order to further understand the shot blasting machine and skillfully use the shot blasting machine in all walks of life, it is necessary to master its working principle.

Shot blasting is a kind of treatment technology in which steel sand and steel shot are thrown down at high speed and impacted on the surface of material objects by shot blasting device. The shot blasting machine strikes the metal surface through one or more kinds of sand, so as to eliminate some attachments on the surface, such as rust. In addition, sometimes a specific surface layer can be obtained by the attack of the shot blasting machine on the metal surface.


Shot blasting machines generally operate through a certain medium, which can be sand of various specifications, silicon carbide particles, small steel balls, etc. The shot blasting machine can also remove sand, core and clean the castings at the same time. Shot blasting machine has a wide range of applications, and its main purpose is to treat the surface of products, such as surface cleaning and polishing of die castings, precision castings, precision forgings and other products; Remove the oxide scale on the surface of heat treated parts, castings and forgings; Surface rust removal of fasteners and steel materials, etc. Even, the shot blasting machine also has the function of strengthening objects, such as strengthening springs.

In a word, the working principle of shot blasting machine is mainly to drop and impact the object surface at high speed through a certain medium, so as to smooth the surface and improve the quality. Making full use of the working principle of the equipment can improve the utilization rate of the equipment.
