Powder flowability and density ratios: the impact of granules packing
TLDR
In this paper, a new flowability criterion based on a novel technique to determine a high packing density was proposed, which is more sensitive to differences in flowability, as quantified by the repose angle.About:

Selected properties of microencapsulated oil powders with commercial preparations of maize OSA starch and trehalose
TL;DR: In this paper, the authors analyzed the properties of high-fat powders, produced upon spray drying of rapeseed oil emulsions stabilized with preparations of OSA starch, and found that the addition of trehalose was the factor that had a greater influence on the properties than the factor of the type of oSA starch preparation.

Effect of superfine-grinding on the physicochemical and antioxidant properties of Lycium ruthenicum Murray powders
Jiangtao Zhang,Jiangtao Zhang,Yushan Dong,Tanzeela Nisar,Zhongxiang Fang,Zi-Chao Wang,Zi-Chao Wang,Yurong Guo,Yurong Guo +8 more
TL;DR: In this article, three different methods were used to ground dry Lycium ruthenicum Murray (LM) fruits and the results suggested that superfine-grinding could be a promising method for producing LM powders with higher contents of bioactive compounds and bioactivity.

Understanding empirical powder flowability criteria scaled by Hausner ratio or Carr index with the analogous viscosity concept
TL;DR: In this article, the authors show that the popular empirical powder flowability criteria scaled with the Hausner ratio or Carr index are theoretically found only to work at special conditions and more universal criteria correlated with shearing conditions and particle physical properties are presented.

Influence of grain size and grain-size distribution on workability of granules with 3D printing
Sebastian Spath,Hermann Seitz +1 more
TL;DR: In this paper, the authors examined how the change in grain size and grain size distribution affects flowability of granules and workability with 3D printing especially during recoating step.

Mixing kinetics of granular materials in drums operated in rolling and cataracting regime
TL;DR: In this article, the authors compare mixing efficiency and kinetics of two different regimes, i.e. rolling and cataracting, aiming at optimising the operation time and the final homogeneity of the mixtures.
