Particle Breakage in Agitated Dryers
AIP Conference Proceedings, 2009A method for predicting particle breakage in agitated dryers is described. The method utilizes an estimation of stresses and strains occurring in a dryer bed sheared by an impeller using the Distinct Element Method (DEM). An assemblage of particles is then subjected to these stresses in a shear cell to assess the extent of attrition under a range of ...

Particle breakage in glacial sediments
2017In most areas of glacial deposits, soils were deposited by ice sheet expansion or contraction, and produced by deformation and mixing of pre-existing soft sediments. The resulting soil (till) is well graded. In some cases the remixing and shearing of sediments by glaciers has caused a redistribution of particle sizes by abrasion and crushing.

Note: Particle adhesion and imaging of particle/surface breakage zone
Review of Scientific Instruments, 2012An AFM methodology to enable measurement of the adhesion of micrometre sized objects, having contact areas in the range of nanometre to micrometer, is reported. The method also enables imaging of the actual breakage zone on both the surface and the removed object to obtain further information regarding the breakage zone.

Effect of Target Walls on the Breakage of Composite Particles
Chemical Engineering & Technology, 2008AbstractThe DEM simulation of the effect of target walls on the comminution of composite particles is studied. Different designs of target walls were considered to achieve the maximum liberation degree, suitable particle size distributions and new surface generation.

Chemical Engineering Research and Design, 2012
Abstract Broadbent and Calcott's breakage matrix methodology has been used for more than 50 years to model various comminution processes and to determine breakage functions from experimental data. The methodology assumes first-order law of breakage and neglects mechanical multi-particle interactions that are especially prevalent in dense-phase ...

Particle Breakage of a Crushed Sandstone–Mudstone Particle Mixture
2021Sandstone–mudstone particle mixture (SMPM) is often used as a main filling material in many agriculture-related and civil engineering works such as in rockfill dams and filling foundations. The SMPM was found crushed seriously since it is mixed with mudstone particles.

A treatment of impact breakage of particles
Powder Technology, 2002Abstract Particles of a given size and material have a distribution of strengths so that some fractions break at low specific strain energies, more at higher strain energies, and all break at sufficient strain energy. Those fragments from breakage at a low specific strain energy produced during a higher specific energy impact will have relaxed their ...
