[0002] ‌Casting shot blasting machine‌ is a kind of equipment that uses high-speed projectiles thrown by the shot blaster to clean and strengthen the surface of castings. It is mainly used to remove pollutants, rust layers, oxide scales, etc. on the surface of castings. At the same time, it can also perform sand dropping, core removal and cleaning on castings. The working principle of the casting shot blasting machine is to throw steel sand or steel shot at high speed through the shot blaster to impact the surface of castings and remove pollutants and rust layers on the surface; At present, the abrasives ejected by the casting shot blasting machine will accumulate on the surface of the workpiece.
