In this setup, compressed air flows rapidly inside the spray gun, creating a negative pressure to draw abrasive materials from the cyclone separator’s tank into the mixing chamber through the sand tube. The abrasive material and compressed air enter the spray gun through the sand tube and air hose, respectively. Inside the spray gun, they combine and enter the carbide nozzle’s converging section. After accelerating inside the straight tube of the carbide nozzle, the abrasive material is ejected from the nozzle’s exit and impacts the surface of the workpiece. This process alters the mechanical properties of the workpiece’s surface, resulting in specific surface effects and achieving the purpose of sandblasting processing.<\/p>\n
