Vertical Screw
Blenders are excellent design
alternatives for product applications
that are shear sensitive, voluminous
and also where space on the plant
floor is at a minimum.
Nauta
mixers are widely used for mixing
dry materials, paste, cream and
lotions. The principle of blending
is based on the differential travel
speeds of product particles in the
conical section of the vessel. The
material from the bottom section
of vessel is lifted by the screw
and spread over the upper sections.
Design
Highlights
The screw
agitator turning on its axis
produces a lifting action as
it spirals the material in an
upward flow
At the same
time the screw orbits the tank
, the screw removes material
away from wall and deflects
it into the centre of the tank
setting up a spiral current
throught the batch
The material
lifted by the screw gravitates
downwards thoroughly intermixing
with material being spiralled
upward.
This
results in most intimate intermingling
of all ingredients
Applications
Dry
powder, resin, urea, paste, cream
, drug

Advantages
When
compared to horizontal blenders
this design has several advantages
The
blending action of the slow turning
screw is far gentler than that taking
place within the horizontal blenders.
Since the active blending volume
at any given time is a lot lesser
than the horizontal blenders, it
results in a lower power requirement.
The large handling capacity coupled
with low power requirement makes
it one of most effective and efficient
Blender within the family.
