Standard Test Method for Carbon Black, Pelleted—Pour Density

4.1 Pour density is a function of the degree of compaction during pelletization. It is strongly influenced by and inversely proportional to structure (OAN). Pour density of carbon black is useful for estimating the weight-to-volume relationship for certain applications, such as automatic batch loading systems, and for estimating weights of bulk shipments.

Analysis of Bulk Density, Bulk Density Content of Biomass ...

At Celignis we determine the bulk density of biomass according to ISO standard 17828 (2015). We use a 5 litre container (certified according to EN 10204-3.1) into which the biomass sample (powder, chips etc.) is poured from a fixed height. The container is then subjected to a defined shock exposure.

Bulk Density - copleyscientific

The bulk density of a powder is measured in a Scott Volumeter. It may be described as the density of the powder "as poured" into a measuring vessel. Tapped density, on the other hand, is the density attained after "tamping down". This is normally measured using an instrument that lifts and then drops a measuring cylinder containing the ...

Bulk Density - an overview | ScienceDirect Topics

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.
