Dispersed agglomerate

A disperse agglomerate is a loosely bound collection of fine particles that are held together by physical forces such as van der Waals forces or capillary forces. These interparticle binding forces can be very strong if the particles are very small.

In general, fluidised bed agglomerates are only moderately stable. However, they are porous and have a low density. They can be easily dissolved or further processed in suitable media or under mechanical stress (e.g. stirring, shearing, mixing).

Dispersed agglomerates are often produced during the moistening of dry, fine powders (amixon® ring layer granulator, granulation drum, fluidised bed mixer/agglomerator). They play an important role in mixing, granulating and tableting technology, e.g. as an intermediate stage in the formation of stable granules or as an undesirable phenomenon in the wet dispersion of pigments.
