Abstract (en)

[origin: WO2019224597A1] The invention relates to an adjustable nozzle, of the type used for liquid or slurry atomization systems, in which the liquid fluid is transformed by the nozzle into a jet or bundle of drops that are introduced countercurrent into a flow of hot air so as to interfer with it and produce a drying of the drops with consequent generation of solid particles with a low moisture content. The nozzle includes adjustment means operated on command from the outside in order to change the characteristics of the nebulized jet or stream of drops emitted by the same nozzle (16). These means include devices that allow the geometry of the passage section of the fluid to be modified in a controlled way so that the flow rate of fluid in the nozzle can be intercepted by partializing it.
