Evolution of particle crushing of coarse-grained materials in large-scale triaxial tests
Yantu gongcheng xuebao, 2020 By analyzing the progressive evolution of particle crushing of crushable soils, four basic properties of particle crushing are presented, and three characteristic states are also given over long-term or repeated loading.

Particle Impact Analysis of Bulk Powder During Pneumatic Conveyance [PDF]
, 2009 Fragmentation of powders during transportation is a common problem for manufacturers of food and pharmaceutical products. We illustrate that the primary cause of breakage is due to inter-particle collisions, rather than particle-wall impacts, and provide

The nonlinear fragmentation equation
, 2007 We study the kinetics of nonlinear irreversible fragmentation. Here fragmentation is induced by interactions/collisions between pairs of particles, and modelled by general classes of interaction kernels, and for several types of breakage models.

Calculating the state parameter in crushable sands [PDF]
, 2019 The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

An application of semigroup theory to a fragmentation equation [PDF]
, 2004 The process of fragmentation arises in many physical situations, including polymer degradation, droplet breakage and rock crushing and grinding. Under suitable assumptions, the evolution of the size distribution c(x, t), where x represents particle size ...
