Dynamic behavior simulation of coal-gangue particles in squirrelcage selectivity sepatation equipment
Abstract：In order to investigate crushing degree of coal-gangue with different roller structure by squirrelcage selectivity sepatation equipment,a discrete element model was established with particle flow code in two dimensions（PFC2D） based on soft ball model,and dynamic behaviors of coal-gangue particles were simulated and analysed with different roller structures.The result shows that crushing degree of coal-gangue is moderate with 6 broken rods.Coal-gangue can not break with 9 broken rods,and coal-gangue may severely break with 3 broken rods.It is shown by the comparisons between numerical results and experimental data that they have good consistency.
