Size Enlargement by Agglomeration | SpringerLink
Abstract. Size enlargement by agglomeration is a unit operation of mechanical process technology 1 (Fig. 6.1). This field deals with the transport phenomena and changes of state of particulate matter which in most cases is solid but can also be liquid (droplets) and, in a few special cases, gaseous (microencapsulated).
Agglomeration (Chapter 6)
Because of its significant effect on product quality, control over agglomeration is important for industrial crystallization (Hollander, 2002). Figures 6.1 to 6.4 show examples of different types of agglomerates. It should be apparent from the pictures that the primary crystals that form agglomerates can be glued together in rather random ways.
