Discrete Element Simulation of Rock Crushing Considering Different Shape

Abstract:

Numerical simulation was conducted to study the particle breakage of rock in rolling compaction (RC) test based on discrete element method (DEM). Different shapes of particles were formed to represent the real particle shape. A quantitative analysis method of particle breakage was proposed according to the grading curve before and after compaction. The numerical results had a good agrrement with the field test, which indicated that the method adopted in this paper was feasibile and could consider the influence of the particle shape on the particle breakage in RC test.
