TLDR
In this paper, the Hosokawa powder tester and Copley tap density volumeter were used to assess the flowability of porous and non-porous powders in which particle size changes as a result of controlling the percentage of fine components in the mixtures.About:

Production of instant soymilk powders by ultrafiltration, spray drying and fluidized bed agglomeration
TL;DR: In this article, an agglomeration of spray-dried powders with maltodextrin as an aqueous binder solution using a fluidized bed agglerator improved the handling and reconstitution properties of the powder.

Reducing CH 4 and CO 2 emissions from waterlogged paddy soil with biochar
TL;DR: In this paper, a potential means to diminish increasing levels of CO2 in the atmosphere is the use of pyrolysis to convert biomass into biochar, which stabilizes the carbon (C) that is then applied to soil.

An overview of powder granulometry on feedstock and part performance in the selective laser melting process
TL;DR: In this article, the current progress of metal AM feedstock and various powder characteristics related to the Selective Laser Melting (SLM) process is addressed, with a focus on the influence of powder granulometry on feedstock.

Characterization of flow properties of cohesive powders: A comparative study of traditional and new testing methods
TL;DR: In this article, the FT4 powder rheometer was used to compare traditional characterization techniques with methodologies provided by the FT 4 powder Rheometer (Freeman Technology) to examine the hypothetical relationships between them and evaluate their ability to discriminate between different powders.
Journal ArticleDOI
Characterization of powder flowability using measurement of angle of repose
TL;DR: In this article, the angle of repose (AOP) is used to measure the flowability of powders in processes involving transport and storage, and the results show that the AOP is consistent with the better known Hausner ratio.

Some considerations on powder compression equations
Kimio Kawakita,Karl-Helmut Lüdde +1 more
TL;DR: There are two approaches to the problem of powder compression: (a) an observation of the relationship between pressure and volume, and (b) the distribution of internal stress and density as mentioned in this paper.

Evaluation of the packing characteristics of mono-sized non-spherical particles
Ruiping Zou,Aibing Yu +1 more
TL;DR: In this paper, the porosity of mono-sized particles is strongly dependent on both particle shape and packing method, and for a given packing method can be approximately by the proper use of the packing results of cylinders and disks.

Fluidization of cohesive powders
TL;DR: In this article, the influence of particle size and other parameters on the fluidization behavior of fine powders has been investigated and can be readily assessed by measuring the ratio of tap to aerated bulk density.

On the Hausner Ratio and its relationship to some properties of metal powders
R.O. Grey,J.K. Beddow +1 more
TL;DR: The Hausner Ratio between the tap density and apparent density of a powder mass is termed as the hausner ratio as mentioned in this paper, which measures the friction condition in a moving powder mass.
