Understanding the interaction between the star wheel arm and coal particles is important to efforts for improving the loading efficiency and reducing the energy consumption of the feeder star wheel. The interaction mechanism between the star wheel arm and coal particles is the theoretical basis of the research. First, the design method of the star wheel arm shape was provided, then a model of the star wheel was constructed with EDEM and a simulation structure. Finally, the influence of the parameters on loading efficiency and energy consumption was determined. Results have been shown that the coal particles in the active zone of the material pile exerts a fluidity effect on loading efficiency and torque. The loading efficiency and energy consumption have been increased with increase in the number of arm and height of the arm. The feeder inclination angle 14° is the best coal loading angle.
