A stochastic particle replacement strategy for simulating breakage
Description of particle breakage embedded in a simulation using the discrete element method (DEM) qualifies it to describe processes in which breakage is either desired or undesired. DEM codes evolved significantly in recent years, many of which describing breakage. In spite of their limitations representing real particles, spheres have An approach for particle breakage simulation based on the framework of discrete element method was proposed in the current study. Convex polyhedron blocks were adopted as elementary particles for the complex particle shapes, and the variability of particle breakage strength is modeled using the invertible function method. Additionally, A discrete element method (DEM)-based approach to simulating particle

Simulation of particle bed breakage by slow compression and impact
Iron ore pellet particle bed breakage by impact and compressive loading were simulated using DEM coupled to a Particle Replacement Model. This particle replacement model has been implemented as a modification of the Hertz-Mindlin contact model and made it possible to replace the initial particles by pre-defined progeny of 2 Particle breakage modeling been verified and validated in detail for several materials on the basis of data from single-particle and unconfined particle-bed impact breakage tests,as well as experiments in a Cone crusher modelling and simulation using DEM.

Numerical simulation of particle breakage in dry impact pulverizer
At the same time, the particle strength as a function of the particle size is calculated from Griffith's theory. If the impact stress is larger than the particle strength, the particle is broken and replaced with smaller fragments. The size distribution of the fragments is obtained from a breakage function proposed.Semantic Scholar extracted view of "Simulation of particle flows and breakage in crushers using DEM: Part 1 Cone crusher modelling and simulation using DEM.

Impact work index prediction from continuum damage model of particle
The rock particle breakage probability under repeated impacts is related to the particle size, impact velocity and number of impacts. Quantifying the effects of these variables on the breakage probability of rock particles provides further understanding of how rock particles behave during the impact process, thereby aiding in the design of more There are many breakage tests used for crusher design estimates.
