Reconstruction granulation
Structural granulation refers to processes in which fine particles gradually build up into larger granules or pellets. The particles move within drums, discs, fluidised beds or ring-layer mixing granulators and repeatedly collide with one another. If they adhere to one another upon impact, the particle grows. Binding liquids or molten phases create liquid or solid bridges between the particles. Agglomeration granulation is a form of agglomeration and is used to convert dusty powders into granules that are easy to dose, free-flowing and stable in storage. Typical objectives include a defined particle size distribution, improved flowability and optimised solubility or wettability.
An important application of agglomeration is pelletisation. In this process, granules are produced from a mixing process, from an inclined turntable or from a rotating tube.
