Available in three sizes
NICA™ S320, NICA™ S450 and NICA™ S700
The NICA™ S320 and S450 are designed for both product development purposes
and small scale production of spherical pellets from extrudate. The Spheronizer
model size denotes the internal bowl size dimension respectively. The S700
Spheronizer ha a typical product capacity of up to 10 kg, providing high
throughput capabilities when lined to the NICA™ System E220 Extruder. Designed
as a production unit, the S700 has an inverter drive and pneumatic discharge as
standard for remote operation and plant integration. In all other respects the
S700 shares the same processing features, easy to clean construction and
up-to-date safety system as its smaller counterparts.
Principles of Operation
The NICA™ Spheronizer
consists of a horizontal spinning wheel with a special friction pattern
machined on its top surface; it rotates within a cylindrical bowl. The
spaghetti-like extrudates are batched and dropped onto the spinning wheel where
they are fractured into short lengths. Interaction between the spinning wheel
and the wall causes the extrudate to be worked into spheres. The size
distribution and suface characteristics of the spheres are controlled by the
batch size, speed, process time and most importantly, by the characteristics of
the extruded mass. The NICA™ Spheronizer has a patented 'smooth edge' on the
friction wheel to eliminate milling of the developing pellets and ensure a
narrow size distribution. Different friction whell patterns can be interchanged
to suit particular requirements. For continuous production, multiple units can
be combined with appropriate up and downstream equipment forming an extremely
compact and flexible package.
