WebTwo or more external factors can cause an otherwise free flowing powder to slow or stop flowing. On the other hand, even a powder with inherent cohesive properties may be processed satisfactorily if the handling conditions are optimized. WebOct 18, 2024 · The powders are lined up from “free flowing” powder to “non-flowing” powder. Flowability of a powder refers to the specific relevant system. The same powder can flow with no issues in one system but will face difficulties in a different pharma equipment. Flowability is a complex factor influenced by multi physical properties.

A powder is called free-flowing if the particles do not stick together. If particles are cohesive, they cling to one another to form aggregates. The significance of cohesion increases with decreasing size of the powder particles; particles smaller than 100 µm are generally cohesive. See more A powder is an assembly of dry particles dispersed in air. If two different powders are mixed perfectly, theoretically, three types of powder mixtures can be obtained: the random mixture, the ordered mixture or the interactive … See more The term ordered mixture was first introduced to describe a completely homogeneous mixture where the two components adhere to each other to form ordered units. However, a completely homogeneous mixture is only achievable in theory and other … See more • Improving Powder Flow During Pharmaceutical Operations, an Rx Times article See more A random mixture can be obtained if two different free-flowing powders of approximately the same particle size, density and shape are mixed (see figure A).
