TLDR
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.Abstract:
The basic integro-differential equation describing comminution process is analytically solved by the use of a certain form of selection function and breakage function. The result agrees well with previous experience. 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. A resulting equation expressing the selection function as a function of particle size, magnitude of force applied and some operational variables as well as material properties is compared with reference data.read more

Evaluation of the Mixing Process Based on a Disintegrating-Rate-Model of the Powder Agglomerates
TL;DR: 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 of 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.

On the Similarity of Austin Model and Kotake–Kanda Model and Implications for Tumbling Ball Mill Scale-up
TL;DR: In this article , the authors investigated the similarities between the Austin model and the Kotake-Kanda (KK) model for the specific breakage rate function in the population balance model (PBM) used for tumbling ball milling and assess feasibility of the KK model for scale-up.
