What Is Agglomeration? | Powder/Bulk Solids

Agglomeration, the sticking of particles to one another or to solid surfaces, is a natural phenomenon. For powders and bulk solids, agglomeration can be unwanted, resulting in uncontrolled buildup, caking, bridging, or lumping. It can also be a beneficial process, utilizing the controlled enlargement of particles to improve powder properties and obtain high-quality products.
