particles; this is known as the 'tapped bulk density.' Bulk density of freeflowing powders or granular materials can be determined by filling a container of known volume, after which the material is weighed and the 'loose bulk density' can be estimated (Fig. 13). The container is then tapped and refilled until the

The wellknown Geldart's [25] powder classification system for gas fluidization was used by Geldart and Williams [26] to characterize the powder flowability on the basis of particle density and mean particle diameter. Under Geldart's criteria, the pulverized coal is a typical group C powder, characterized by poor flowability and strong cohesive forces.

Bulk density is the mass of bulk solid that occupies a unit volume of a bed, including the volume of all interparticles voids. Taking into account that a powder is really a particle gas mixture with both interparticle spaces and intraparticle voids (Fitzpatrick et al., 2013), three classes of bulk density have become conventional: aerated, poured, and tap.
