Abstract. Application of the discrete element method for modeling of rocks crushing in a jaw crusher is considered. Interaction between the jaw crusher walls and the bulk material under processing is studied. The process of modeling is examined stage by stage starting from the crusher construction design in solid and surface-modeling system Solid Edge. Modelling of the crushing process is based on experimental data obtained using the crushing unit BOYD. Results of the study of the material crushing process and size distribution of the rock mass pieces are presented. Comparative analysis of actual experimental data with the modeling process is performed.
Keywords: modeling, jaw crusher, discrete element method, crushing, coarse crushing
