Spraying Granulators  Manufacturers, Traders, Suppliers

Spray granulation is a combination of fluid-bed drying and spray drying.  The individual powder particles in the fine-grain seed material are combined into larger agglomerates.  Unlike the case with compactors, however, there are no external forces acting on the agglomerates.  This process is consequently also referred to as pelletizing.  Fluid-bed agglomerates have a porous structure and are easily dissolved or dispersed.
The receiving liquid (suspension or solution) is sprayed onto the fluidized seed material.  Some of the solvent is evaporated in the air stream and also in the fluid bed.  Due to the combination with PERGANDE high-performance fine-dust filter technology, seed material can be fed in permanently as a result of returning the filter cake to the fluid bed.
