NOZZLE CONFIGURATIONS:
ROTARY
ATOMIZER Atomization is achieved by feeding liquid into a
high-speed wheel. The rotary atomizer is placed in the ceiling air disperser
and operates with a vaned atomizer wheel for non-abrasive feeds, and with a
carbide bushing wheel for abrasive feeds. Other designs are available for
special applications. Powders produced with this atomizer mode have a narrow
particle size distribution with a mean size in the range of 20-50 µm.
TWO-FLUID NOZZLE, CO-CURRENT MODE Atomization is
achieved by using compressed air to atomize the liquid feed. The nozzle placed
in the ceiling air disperser is ideal for heat sensitive feeds and has the
added advantage of handling both low and high viscosity feeds. Powders produced
with the co-current two-fluid nozzle have a mean particle size in the range of
10-40 µm.
TWO-FLUID NOZZLE, FOUNTAIN MODE The
nozzle placed in the cone section of the drying chamber is spraying upwards
counter-current into hot air from the ceiling air disperser. The fountain mode
has the advantage of spray drying high solids feeds, and producing free-flowing
powders of a mean particle size in the range of 60-100 µm.
