TL;DR: In this paper, a mathematical model was developed to predict the transitions between different forms of transverse motion of free-flowing bed materials in rotating cylinders: sliding, surging, slumping and cascading.

TL;DR: In this article, the effect of variables such as rotational speed, bed depth, cylinder diameter, particle size, and particle shape on bed motion has been determined, and the scaling of bed behavior with respect to particle size and cylinder diameter requires similarity of Froude number modified by(D/d p)1/2, and pct fill.
Abstract: Slumping and rolling beds have been studied extensively in a continuous pilot kiln and batch rotary cylinders. Solids investigated include nickel oxide pellets, limestone, sand, and gravel. The effect of variables such as rotational speed, bed depth, cylinder diameter, particle size, and particle shape on bed motion has been determined. For a given material, the different modes of bed motion can be delineated conveniently on a Bed Behavior Diagram which is a plot of bed depthvs rotational speed. The scaling of bed behavior with respect to particle size and cylinder diameter requires similarity of Froude number modified by(D/d
p)1/2, and pct fill. Measurements of key variables characterizing slumping and rolling beds have also been made.

TL;DR: In this paper, the authors present a mill scale-up procedure based on population balance models of grinding circuits, which can be applied to the design of continuous grinding circuits for dry ball milling of limestone.

TL;DR: In this paper, a relation between the breakage of food particles by the teeth and their material properties has been found, and the finding has considerable implications for human masticatory studies, for the analysis of dentition and diet in mammals and for texture studies in food science.
