Haufners ratio
WebAnother way to measure the flow of a powder is the Hausner ratio, which can be expressed as = /. Both the Hausner ratio and the Carr index are sometimes criticized, despite their relationships to flowability being established empirically, as not having a strong theoretical basis. Use of these measures persists, however, because the equipment ... WebThe Hausner ratio is a number that is correlated to the flowability of a powder or granular material.

WebWhat is a good Hausner Ratio? 1.25 The ratio of tapped density W/V 50 to fluffy density (W/V 0 g/ml) is known as the Hausner ratio. A good flow is indicated by a Hausner ratio greater than 1.25, and a poor flow may have a value of 1.5.
WebThe Compressibility Index and Hausner Ratio are measures of the propensity of a powder to be compressed. As such, they are measures of the relative importance of interparticulate interactions. In a free-flowing powder, such interactions are generally less significant, and the bulk and tapped densities will be closer in value. ...
