DEM exploration of the effect of particle shape on particle breakage in granular assemblies

Computers and geotechnics, 2020
The effect of particle shape on particle breakage is investigated through triaxial tests on sand assemblies mixed with non-spherical agglomerates using the discrete element method.

Effects of particle sizes on compressive deformation and particle breakage of gangue used for coal mine goaf backfill

, 2020
Broken gangue from the collapsing roof of a longwall coal panel can be used as the backfilling material for goaf backfilling. The particle size gradation has important influence on the compressive deformation of the gangue backfilling material and ...

Modelling of particle breakage during drying

Chemical Engineering and Processing: Process Intensification, 2008
An advanced theoretical drying model of single wet particle is proposed. The temperature profile in both crust and wet core regions is described by partial differential equations with appropriate boundary conditions. A Stefan-type vapour diffusion through the crust pores and its convection to the drying ambient has been assumed.

Simulation of Spherical Particle Breakage

2014
Abstract Many papers on particle breakage provide qualitative descriptions of changes in particle shape, but do not provide quantitative analysis of changes in the particle shape. The papers that provide quantitative analysis often focus on the case where corners are chipped off of a cubic crystal.

Effect of Breakage on the Bipolarly Charged Particles

Advanced Materials Research, 2013
The population balance equation (PBE) was solved numerically by using the sectional method to investigate the effect of breakage on the agglomeration between bipolarly charged particles. Calculations showed that breakage results in the increase of small particles and the decrease of large particles bipolarly charged, compared to the case with only ...

Particle Breakage and the Drained Shear Behavior of Sands

International Journal of Geomechanics, 2017
This paper presents particle breakage and the drained shear behavior of sands. A series of drained shear tests were conducted on Silica Sand No. 5 and Coral Sand No. 3 under a 3-MPa confining pressure to produce the precrushed sands that were reused in triaxial tests to detect the influence of particle breakage.
