1. General description of Fluid Bed Granulator
In the fluid bed granulator, the powder in the container (fluidization) appears in the state of fluidization. It is preheated by clean hot air. At the same time, the solution of adhesive solvent is fogged and sprayed into the container, which turns particles into granules containing adhesive. With continuous drying through hot air, the moisture in the granulation is evaporated and the adhesive is solidification. The process is carried out continuously. Finally, it forms ideal, uniform and porous granules.

3. Features of Fluid bed granulator
1, Mixing-granulating-drying in one-step.
2, Adopting double chamber filtering bags system, removing dust completely.
3, Adopting multi-fluid nozzle, it guarantees that the formed granule is uniform and the content of powder is low.
4, Can choose 2 bar explosion-proof design
5, Designed, manufactured and laid out by GMP
