Abstract

Through the rapid quantitative loading system, a large amount of coal bulk material is loaded into train or car carriages. In the process of coal loading, the eccentric loading problem often occurs because of the uneven distribution of accumulation density. The discrete element method is applied to establish the simulation model of the coal loading system, and the complex particle model with different shapes is introduced. The accumulation characteristics of bulk material at different moments during the coal loading process are analyzed, and the accumulation distribution characteristics of different types of particles are analyzed. The hierarchical distribution law of coal bulk layered accumulation density in the carriage is obtained, which provides a theoretical basis for the uniform loading of coal bulk.
