The
Kneader Extruder combines the efficiency of
a double arm mixer with the convenience of extrusion
screws for improved mixing and discharge of
heavy viscous materials.
The Kneader
Extruder includes a set of contra-rotating kneading
blades and one or more extrusion screws. The
blades are mounted on a horizontal axis in a
W-shaped trough. Below the blades in a separate
cavity are the extrusion screws. During the
mixing cycle the blades rotate towards each
other while the mixing screws rotate in a reverse
direction, constantly feeding new materials
into the mixing blades. After the mixing/kneading
cycle is complete, the screws are reversed and
they extrude and transport the mixed materials
out of the mix zone.
Type
of Blades
Sigma
Sigma
blades are best suited for all round
use. These may be positioned with
either tangential or overlapping
action. Both actions provide excellent
mixing characteristics.
Spiral
Spiral
blades provide excellent mixing
for fiber-reinforced products. These
do not have the same heavy - duty
shearing action like other blades
and therefore produce a smooth homogenous
mix with no fiber breakdown.
Masticator
Masticator
blades provide excellent mixing
and kneading action for highly viscous,
tough masses. These are widely used
by the rubber industry in Dispersion
Kneaders and Intermixes.
Naben
Naben
blades produce extra shearing action
required for certain materials. The
blade geometry resists distortion
from stresses in the mixing load.
These are available in both tangential
and overlapping action mixers.

Applications
Ideal for mixing, kneading
of highly viscous mass, sticky and dough
like products.
Mixing of pastes, rubber,
and heavy plastic masses.
Applications in Food,
Rubber, Pharmaceutical and Chemical
industries.
Dry powder to wet phase
mixing.
Advantages over
conventional tilting bottom discharge kneaders:
Low mixing time.
Continuous operation possible
because of extrusion screw.
Elimination of the manual
scraping of sticky/tacky materials.
Eliminates operator exposure
to materials at elevated temperatures or those
of a toxic nature, thereby improving plant
safety.
