Numerical investigation of particle breakage as

The investigation of such behaviour requires good modelling of the breakage conditions of a single particle subjected to multiple loads from neighbouring particles [3]. For this reason, confined conditions are required in simulating particle breakage for the understanding of the interparticle breakage behaviour.

DEM Modeling of Particle Breakage in Silica Sands

A Discrete Element Method (DEM) model is developed to study the particle breakage effect on the one-dimensional compression behavior of silica sands. The ‘maximum tensile stress’ breakage criterion considering multiple contacts is adopted to simulate the crushing of circular particles in the DEM.

Dynamic Modeling and Analysis of a Novel 6-DOF

This paper proposes a novel 6-DOF robotic crusher that combines the performance characteristics of the cone crusher and parallel robot, such as interparticle breakage and high flexibility. Kinematics and dynamics are derived from the no-load and crushing parts in order to clearly describe the whole crushing process. For the no-load case, the kinematic and dynamic equations are established by ...
