Estimation of New Surface Generation and Energy Analysis during Particle Fracture

摘要

Breakage of particles is a common phenomenon in handling, storage, transportation and processing of particles. Severity of breakage depends on particle loading types and environment as well as on the particle properties and strengths. The loading energy applied to the particle is used to generate new surfaces in the particles; as a result fragmentation of particles occurs. In this regard, the paper estimates the new surface generation during particle fracture using discrete element modeling. The paper also deals with the compression and impact loading of particles.
