Abstract: In order to illustrate the performance characteristics of two commonly used vibrating feeders in coal ports in our country, this paper starts with the analysis of the force on the vibrating bed by particles, and obtains the demarcation point of skidding, jumping and quiescence. By using analytical and geometric methods, According to the actual structure size of the feeder, the maximum feed particle size, the maximum feeding amount, geometric angle of rest and power efficiency, area efficiency and volumetric efficiency were found out. For the majority of users on the feeder selection and use provides a more detailed theoretical basis.
