Evaluation of the mixing process based on a disintegrating rate model of the powder agglomerates
TLDR
In this paper, the authors described the mixing process of powders in an agitation type of solid mixer based on a modified comminution model and expressed the mixing procedure for the fine and adhesive powders by means of the disintegration process of the tracer agglomerates (ironoxide) in the bulk powder bed (calcium carbonate) in this model.About:

An experimentally validated DEM study of powder mixing in a paddle blade mixer
TL;DR: In this paper, the predictive capabilities of Discrete Element Method simulations of a powder mixing process in a laboratory scale paddle blade mixer is presented. But the mixing was under-predicted in the simulations, suggesting that flow energy measurements alone may not be sufficient for the optimization of a DEM model of powder mixing.

Pharmaceutical dry powder blending and scale-up: Maintaining equivalent mixing conditions using a coloured tracer powder
TL;DR: In this paper, a series of lactose powders (white) with 1.5% sub-micronised iron oxide tracer (dark red) by weight were blended with three different mixing technologies under a range of processing conditions.

The mechanism of agglomeration of the refractory materials in a fluidized-bed reactor
TL;DR: In this paper, the authors investigate the mechanism of olivine agglomeration in fluidized-bed reactors and to determine the risk factors for aggloomation, which is one of the refractory materials wellsuited for fluidized bed reactor technology.

Improving the homogeneity and properties of ferrous powder mixes by a novel powder mixing process
TL;DR: In this article, the Fe-2Cu-0.8C powder mixes were prepared by a wet mixing and spray-drying process using iron, copper, graphite and zinc stearate as main raw materials, and stearic acid, alcohol wax and amide wax as...

Analysis of the selection function of comminution kinetics
Masaji Hayashi,Tatsuo Tanaka +1 more
TL;DR: In this article, the basic integro-differential equation describing comminution process is analytically solved by the use of a certain form of selection function and breakage function, and the rate constant of the selection function is considered in relation to the stress field produced within a powder bed and to the strength of material crushed.
