Criteria and Phenomena of Agglomeration

Both the attraction and environmental forces are mainly dependent on the size X of the powder particles. To cause adhesion, must be larger than unity. In most cases, to keep the particle(s) adhering, the sum of all moments, Qj(x must also be zero  

It will be shown later that most of the attraction forces have only a short range their magnitude and strength decrease quickly with increasing distance. 

The multitude of possible binding and attraction forces acting in a network of particles can result in agglomeration, even if some individual particles do
