The Hausner Ratio is a measure of the flowability of a powder, calculated as the ratio of tapped density to bulk density. It is used to predict powder behavior during handling and processing, with higher values indicating poorer flowability and potential handling issues.

Hausner Ratio

Flowability of a powder

Tapped density is the measurement of the bulk density of a powder after it has been mechanically tapped or vibrated to reach a steady state of compaction. It is a crucial parameter in industries like pharmaceuticals and material science, where it helps evaluate flow properties and packing efficiency of powders.

Tapped Density

Bulk density is a measure of the mass of a material per unit volume, including the void spaces between particles. It is a critical parameter in fields like agriculture, geology, and material science, influencing properties such as compaction, porosity, and water retention.
