Effect of particle shape and size on flow properties of lactose powders
TL;DR: In this article, the influence of particle shape/size of three different lactose powders on their respective flow and bulk characteristics has been quantified, and the results demonstrate that in addition to particle size, particle shape significantly affect the flow characteristics of a powder over a wide range of stress conditions.
