Use of the attainable region analysis to optimize particle breakage in a ball mill
TL;DR: In this paper, the authors use the attainable region (AR) analysis to optimize the comminution of silica sand particles in a bench top laboratory ball mill and show that when the mill is loaded with a large number of grinding media (J=volume of media/mill volume=10.7%), the breakage profiles are indistinguishable over all rotation rates investigated.

Simulation of the breakage of bonded agglomerates in a ball mill
TL;DR: In this article, the effect of agglomerate bond strength and grinding media diameter on breakage and flow was analyzed using the Attainable Region (AR) approach, and it was shown that the majority of breakage occurs near the mill shell, rather than at the point of impact between the media and material.

A solution to the batch grinding equation
TL;DR: In this article, a practical approximation to the fundamental integro-differential equation for batch grinding is presented and a solution is developed in terms of two experimentally determined basic parameters of the system, rates of breakage and breakage function, and is in a form suitable for simple extension to describe continuous grinding systems.
