On the progressive nature of grain crushing [PDF]

open access: yesEPJ Web of Conferences, 2017
In this work acoustic emission (AE) is used as experimental evidence of the progressive nature of grain crushing. Stress controlled high pressure oedometric compression test are carried out on 1.2 mm monodisperse samples of glass beads.

Particle Crushing and Deformation Behaviour

open access: yesSoils and Foundations, 2009
Particle breakage occurs in granular materials with various engineering applications, such as when driving piles (especially where the strength of the particles is low) and in debris flows (where the energy levels are high), and the influence of this breakage on the mechanical behaviour of soils should be given proper consideration in a constitutive ...

Effects of controllable shock wave on particle size characteristics of tin polymetallic ore crushing products

open access: yesJournal of Materials Research and Technology, 2023
Different minerals in tin polymetallic ores have varying degrees of grindability. When the particle size distribution of the crushed ore is unreasonable, sufficient liberation of useful minerals necessitates an increase in the grinding time, resulting in

Fractal Behavior of Coral Sand During Creep

open access: yesFrontiers in Earth Science, 2020
Granular materials undergo particle crushing under the long-term load, which changes the particle size distribution (PSD) of the material, and then affects its mechanical properties, so the problem of its long-term stability issues is outstanding ...
