Rotary Index Tables have many applications in manufacturing including machining assembly inspection and welding. The values of Carrs index and Hausners quantitative relation was in between 116-125 and 011 to 025 indicating that each one batch of powder blends was having well squeezability. A Carr index less than 21 for a powder mixture indicates good flow while one between 21 and 25 suggests a marginal flow property.

Compressibility Index Hausner Ratio The two most commonly used measures of the relative importance of interparticulate interactions are the compressibility index often referred to as Carrs. 101 and 102 respectively where ρb is the bulk density and ρt is the tapped density of each material He 2009. For example 5-15 and bulk powder density is a process indicates excellent 12-16 good 18-21 fair critical measurement for many industrial and 23 poor flow.

The following is a summary from USP The widespread use of powders in the pharmaceutical industry has generated a variety of methods for characterizing powder flow. The Carr index is calculated by the formula where is the freely settled volume of a given mass of powder and is the tapped volume of the same mass of powder. Some tests such as Carrs compressibility index Hausner ratio and the angle of repose were applied to evaluate the flowability of yogurt powder.

Evaluation results of comparable parameters. Before moving to Wilsons current city of Fairfax VA Wilson lived in Berryville VA. Measures of Compressibilty Index and Hausner Ratio -Because the interparticulate interactions influencing the bulking properties of a powder are also the interactions that interfere with powder flow a comparison of the bulk and tapped densities can give a measure of the relative importance of these interactions in a given powder.

It was found that the Carrs Index C an overall manifestation of particle size distribution of only a few grams of the dry blended acetaminophen was good enough to be linearly related to the dissolution rate constant k of the formulated granules by ln k alpha ln C ln A or exponentially by a power law of k ACalpha where A was the. The compressibility index often referred to as. We have lots of information about Wilson.
