Dry stacking of iron ore tailings: Possible particle breakage during compaction
Geotechnical Engineering, 2023The disposal of iron ore tailings in dry stacks has become increasingly common in Brazil. In these structures, the iron ore tailings are compacted in layers using drum rollers that cause compaction and vibration efforts on the ground.

Breakage of anisometric rod-shaped particles
Particulate Science and Technology, 2017ABSTRACTIn this experimental study, behavior of dry granular layers of monodisperse cylindrical particles (8 × 1 mm) under uniaxial compression in piston die arrangement was investigated. The layer compressibility and particle size distribution (PSD) were measured.

Impact breakage of particle agglomerates
International Journal of Mineral Processing, 2001Abstract The paper examines the various factors that influence the breakage of particle agglomerates resulting from impact. Numerical simulations of polydisperse spherical agglomerates impacting orthogonally on a target wall have been performed to study the effects of impact velocity, solid fraction, contact density, and the local arrangement of ...

Particle breakage in transitional soils
2017Oedometer tests were conducted to investigate whether particle breakage plays a significant role in the compression of transitional soils. Artificial mixtures of a carbonate sand and kaolin or a crushed quartz silt were both found to give measurable breakage within the sand fraction even at modest stresses, which is in contrast to the findings from ...

Modeling the Particle Breakage via Breakage Energy during Triaxial Shearing
Journal of Testing and Evaluation, 2022Abstract Rockfill materials are widely used as foundation in construction and different degrees of particle breakage inevitably show different characteristics. The breakage index (e.g., Marsal breakage index, Bg) of rockfill materials directly measured though experimental method naturally has an intrinsic correlation with the physical ...

Statistics of multiple particle breakage
AIChE Journal, 1996AbstractA method for generating theoretical breakage distribution functions for multiple particle breakage is presented. It starts with the joint probability function that accounts for all the child particles; it is then reduced to the marginal probability function commonly used in the breakage equation. This method is flexible enough to allow the user
