Powder flowability

Why Measure Powder Flowability?

Accurate measurement of powder flowability is indispensable in industries such as pharmaceuticals, food processing, and materials science. Poor flowability can lead to challenges like uneven mixing, difficulties in tablet compression, and inconsistent filling of capsules. By assessing flow characteristics, manufacturers can identify and address potential issues early in the production process, ensuring product quality and process efficiency.
Flowability is influenced by many factors, such as particle size distribution, particle shape, density, and electrostatic state,… It can be simply evaluated using only one parameter, such as the angle of repose, the compressibility, or the angle of spatula. However, flowability is a property related to various indices, which can be expressed more rigorously as the weighted sum of many parameters associated with powder characterization. It can be measured using various techniques and instruments. The choice of method depends on factors such as the nature of the powder, the specific properties to be assessed, and the intended application.
