The Hausner ratio is a number that is correlated to the flowability of a powder or granular material. It is named after the engineer Henry H. Hausner (1900–1995). The Hausner ratio is calculated by the formula where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder. The Hausner ratio is not an absolute property of a material; its value can vary depending on the … http://aimsizer.com/tapped-density-testers-images-and-pictures/measures-of-compressibilty-index-carr-s-index-and-hausner-ratio.pdf

WebMar 22, 2024 · Obtained granulates had good mass flow rates (5.5 ± 0.3 g/min) and Hausner ratio (1.09) at given D 50 particle size of 137.5 µm and have satisfied the tableting requirements. The high-speed tableting process at different tableting compaction force was in the range of 4.8–15.5 kN and was illustrated with the Heckel plot, manufacturability ... WebCarr index. The Carr index (also: Carr's index [1] or Carr's Compressibility Index [2]) is an indicator of the compressibility of a powder. It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula , where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after ...
