Why Agglomerate Powder? - FEECO International Inc.

A lack of flowability is one of the most common reasons for which producers decide to agglomerate a powdered material or product. The rheology of powders, while varying from one material to the next, makes powder generally less flowable than a granular product. When powder is agglomerated, however, particularly by wet granulation (also known as ...
