Process advantages
Enables different processes to be used for the rapid, economical
manufacture of round pellets with very narrow grain size distribution.
Principle of operation
In the Spheronizer/Pelletizer
moist granules or pre-formed extrusion products are fed onto the
rotating pelletizer plate.
The rotation of the plate, the force of the incoming product and
the air entering from the air gap at the side produce a uniform
movement of the product along a spiral path at the wall of the container.
The surface is smoothed due to the intensive rolling movement and
pellets are produced. Dust particles resulting from this are rolled
up again directly in the course of the process and bonded into the
pellet.
Several spheronizers/pelletizers can be connected in cascade in
order to increase the batch throughput. Cascades also allow layer
structures to be built up. In this case, the upstream granulation
process is a deciding factor in the structure of the pellets.
The most frequent combinations are Vertical
Granulator and spheronizer/pelletizer or extruder and spheronizer/pelletizer.
