The spray granulation process converts a water-containing solution, paste or suspension or a melt into a granule. The granulation and the drying processes take place at the same time. Any kind of crystallization and mechanical dewatering equipment can be replaced by an SGS type fluid bed. The final product granules are dust-free and easy to handle.
The purpose of the spray granulation process is to generate a particle with a defined structure, size, shape, and composition. In comparison to mechanical granulation processes, the spray granulation process has some major advantages related to the quality of the final product, such as:
Almost spherical shape
High bulk density
Perfect flow characteristics without attrition
Narrow particle size distribution
Good transport, storage, dosing, screening, and packing properties
