Granulation refers to the process by which small particles are grown into larger particles. This process can be desirable when larger particles are needed for applications or materials handling. Or granulation can be undesirable when particles stick together and form unwanted aggregates. An important area in powder handling is avoiding "self-granulation" where a powder or granular material changes its particle size and bulk density as a result of handling. This can cause an otherwise acceptable material to not match performance specifications.
The REVOLUTION Powder Analyzer measure granulation potential by determining the initial powder flow properties of a material and then exposing the material to granulation forces. If the material granulates, typically the bulk density and flow properties change as a result of the increase in particle size of the material.
