4. Agglomerate structure and size
The properties of agglomerates (size, density, shape, etc.) govern their macroscopic behavior in fluidization. The structure of agglomerates is largely determined by the characteristics of the primary particles: size, density, shape, nature of the material, nature of the interparticle forces, etc. However, the state of knowledge is such that it remains difficult to predict the structure of agglomerates. Nevertheless, the state of our knowledge is such that it remains difficult to predict the structure of agglomerates and their macroscopic behavior from the properties of the primary particles.
In general, primary particles can be bound by two mechanisms:
aggregation: an aggregate is an assembly of particles bound together "rigidly", often by sintering. Aggregates become indivisible...
