A peridynamic investigation on crushing of sand particles
Particle crushing underpins important macroscopic behaviour of granular materials such as yielding, deformation, dilatancy, failure, mobility and packing features. …
Particle crushing in hydrate-bearing sands
Sand crushing may become detrimental to gas production, because the breakage of sand particles can cause sediment contraction, reduction in permeability, and the generation of finer particles exacerbating solids migration and sand production. This study experimentally investigates particle crushing in tetrahydrofuran hydrate-bearing …
Acoustic Emission and Force Drop in Grain Crushing of Carbonate Sands
AbstractThe crushing behavior of carbonate sand, due to its porous and fragile structure, exerts a significant influence on the construction of coastal engineering. The collapse of porous material usually produces elastic wave dissipation and force drop ...

Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …
Impact of Particle Shape on Crushing Behaviour of Rock
The crushing fragments (LBS sand, HDG sand) from single-particle crushing tests usually have low values of shape parameters with high dispersion, while the fragments (Reigate sand, calcareous sand, RBS sand, and carbonate sand) in oedometer/triaxial tests present relatively high values of shape parameters with low …
