(pdf-file 290.36 KB)The process of particle size enlargement can change the properties of granular materials significantly. By agglomeration fine-sized primary particles are transformed into free-flowing and dustless consumer products. Usually this is achieved by the addition of an aqueous binder forming liquid bridges between the primary particles. To solidify the binder bridges the solvent needs to be removed by a drying process. The fluid bed technology is one possibility to combine both agglomeration and drying in a single apparatus. This technology can be used either for batch operation or in continuous operation mode, depending on the product specification, throughput or production costs. For the design of production plants fundamental knowledge of the relationship between governing process parameters and the resulting product properties is desired. Such knowledge can be implemented in simulation models, providing a framework to support the plant design.
