Working Principles
The Machine consist of a motor/blower assembly, a nozzle system, nozzles housing, a formulation
tank and a metering valve.The various components are identified in a digramm below.The blower
is a single stage/centrifugal impeller/axial flow driven by a universal motor operating at a speed of
about 20.000 rpm.The blower moves a large amount of air through the noozle system consisting of
three individual noozles, each of which has two sets of directing vanes. One vane set causes the air
to be rotated clockwise and the other causes forces shears the material being dispensed into small
particles.Further the air rushing by the specially shaped liquid tubes creates a negative pressure in
the liquid tube. This negative pressure causes the liquid to the drawn from the formulation tank
through the control valve and into the nozzle system where it is pneumatically sheared into aerosol
or mist size droplets.After breack-up, the droplets are driven away from the machine by the air
passing through the noozle system.
Generally, the size of the output droplets increases with increasing flow rate and
with increasing viscosity.
