Pelletizing in an High Shear granulator
To form granules out of powders a granulation liquid and mechanical energy is needed.
Wet Pelletizing
This process uses a Niro Rotary Atomiser spray to achieve excellent dispersion of binder liquid through the mix, and a special high-speed rotation blade for maximum movement of the product, for more efficient pelletization. A PTFE container-lining minimises the need for ‘top and tailing’, even with the most cohesive of products. In a typical set-up all ingredients are pre-blended in a
container after dispensing. Depending on the extruder design the liquid can be added in the extruder or mixed separately to the correct consistency.
Melt Pelletizing
This is an exceptionally fast method of producing pellets in a single step. The active material and
binder are mixed in binder form then heated until the binder melts. A single batch is processed
typically in just 15-20minutes, and needs no further drying.
