Two basic types of nozzles are commonly used in
spray drying equipments.
»
Pressure Nozzle
|
Pressure nozzle or single fluid nozzle use pressure
energy for atomization, with feed pressures in the range of 200
to 600 psi. The pressure energy is converted into kinetic energy
and the feed issues from the nozzle has a high- speed film which
readily breaks. The pressure nozzles are suitable for feed with
relatively low viscosity and free of lumps. |
»
Pneumatic Nozzle
|
Pneumatic or Two Fluid
Nozzle use compressed air to provide the energy required for
atomization. Compressed air pressure is usually in the range 20
-100 psig. Feed pressure requirement is low and viscous feed is
handled successfully. In pneumatic nozzle the feed can be mixed
with compressed air either internally or externally. The
external mixing types are used for abrasive feeds. Two Fluid
Nozzle atomizer are convenient for low capacity application and
popularly used for high quality ceramic powders: Alumina,
Bentonite, Carbides, Clays, Ferrites, Steatites, Titanates and
Zirconias. |
