The average particle size of 3 common kinds of spray shape


Following, LORRIC use laser diffraction particle size analyzer to get the particle sizes of 3 different kinds of nozzle which is under 2kg pressure and 2Lpm flow rate.


Various nozzles Average spray particle size Comparison of particle size

Cone shape

274um Coarse

Fan shape

234um Fine

Hollow Cone

221um Finest


Features of particle size


◉ Smaller the flow rate, finer the particle size.

◉ Greater the pressure, finer the particle size.

◉ Particle size will be varied by nozzles with different structure.
