Fluidized bed technology provides one possible method to achieve particle size enlargement, creating desired physical properties such as improving powder flow and dust elimination. This is typically achieved through 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. Fundamental knowledge of the relationship between governing process parameters and the resulting product properties is desired for the design of production plants. Such knowledge can be implemented in simulation models, providing a framework to support
