In this study, the fracture phenomenon of particle impacting with wall was directly observed using a high-speed camera. The results from the experiments indicate that the fracture behavior differs in the impact angle, and there are two types of fracture mode: one is with “Break” and the other with “Chip”. In case of low impact angle condition (less than 70°), there is only “Chip” mode. Furthermore, the effect of the particle impact angle on particle fracture phenomena was also investigated. The results of this study indicate that the particle fracture velocity almost is the same value at impact angles under 45° or higher.
