Long venturi nozzle has the structure with the converging section, straight section and diffuser
section. Compared with the straight hole nozzle, it has better function of gas dynamics, strong
improvement in vortex, less pressure loss. Under same pressure, the exit velocity of sandblasting
meterials almost doubles as the speed of voice, resulting in higher momentum of the abrasives,
increased impact energy and added effectiveness of cleaning
