Angle of Repose Angle of Fall Angle of Difference Angle

Angle of Repose Under the static balance the angle between the slope of a powder pile and the horizontal plane is Angle of Repose. It is measured when the powders fall to a surface via gravity and form a cone. It indicates the flowability of the powders. The smaller the Angle of Repose is the better the flowability of the powders.

Angle of Reposean overview ScienceDirect Topics

Jamie Clayton in Handbook of Pharmaceutical Wet Granulation 2019. 4.1.1 Data Generated. All of these techniques provide a flowability ranking based on the measured parameter. For example a powder with an angle of repose of 66° would be classified as having extremely poor flow properties compared with one with an angle of 25°–30° which would be classified as "free-flowing."

Journal of Chemical and Pharmaceutical Research

The granules were evaluated for various parameters such as angle of repose hausner`s ratio Carr`s compressibility index and sieve analysis. Angle of repose - The angle of repose is a relatively simple technique for estimation of the flow property of a powder. Powders with low angle of repose are free flowing and those with a high angle of repose

General Chapters <1174> POWDER FLOW

Drained angle of repose is determined by allowing an excess quantity of material positioned above a fixed diameter base to "drain" from the container. Formation of a cone of powder on the fixed diameter base allows determination of the drained angle of repose. Dynamic angle of repose is determined by filling a cylinder (with a clear flat cover on one end) and rotating it at a specified speed.
