This paper presents an investigation into the roll compression induced breakage process of a coal prism within a vertical roller mill. The targeted process was characterized by strong nonlinearities arisen from large deformation, and from original continuum to final discontinuum. A numerical approach coupling the Smoothed Particle Hydrodynamics (SPH) method and the finite …
