Basket Extrusion
Basket Extruders
We
manufacture
Basket Extruders provide the lowest pressure method
of wet extrusion combined with moderate sheer. To form
granules from 0.5 to 5.0 mm in diameter our basket
extruders provide a
very versatile means of wet extrusion They produce
consistent extrudates from
wetted powders at laboratory through multiple ton
per hour extrusion capacities.
In the upper
chamber of our basket extruders the counter rotating internal breaker bar
system breaks larger clumps of wetted feed material to allow
gravity to convey the wetted mass down into the bottom
extrusion rotor arms which, in turn, densifies the material and
extrudes it through the screen basket. Formed
extrudates are discharged without damage by our
proprietary discharge chute design.
Product extruded
with our basket extruders have a stable
structure with a large surface area which provide
the optimum pliable properties for
Spheronization.
Basket Extruder models are
available with capacities from bench level scale to over
3,000 Kg/hr.
Separate basket
extruder designs
for pharmaceutical and industrial applications are
available. All extruder models are easily cleaned and have
appropriate shaft seals protecting the feed material
from contamination. All process wetted
components are made available per FDA or industrial
requirements. Metallurgies include: 316L, 316,
304, as well as more exotic metals
Our Basket Extruders include:
•
Adjustable angle and gap between rotor blades and
basket screen allows optimization
of
extrusion force
•
Short active extrusion path minimizing temperature
rise for heat sensitive actives
•
Narrow particle size distribution
•
Very high capacities up to 3,000 kilograms per hour
•
Screen sizes from 0.3 to 5.0 mm
•
Extrudates well suited for
Spheronization
•
Appropriate electrical panels and drives for
explosion proof operation
Basket Extruder
Significant Features:
Simple free falling discharge
Adjustable wiping blades
Internal counter rotating breaker bar keeps material from
sticking together
High capacity
Safety switch prevents operation when screen
removed
Proven in multiple Industries:
Basket Extruders have proven successful in many
industries, including pharmaceutical, agricultural
chemicals, and inorganic chemicals among others.
Example Applications:
Forming pharmaceutical extrudates prior to
Spheronization for controlled release
applications
