(1) Compared with the airflow type, it greatly saves the power for atomization.
(2) The structure is simple and the manufacturing cost is low.
(3) Easy operation, convenient replacement and maintenance. .
For low-viscosity materials, pressure nozzles are more suitable. Since the pressure type nozzle produces larger droplets than the airflow type, pressure spray nozzles (sometimes also rotating disc atomizers) are generally used for spray granulation. Such as washing powder, instant milk powder, granular fuel, etc. all use pressure nozzles.
