Abstract: Taking a common relative revolving feeder head as research object, the work mechanism of the feeder head and the material kinematics in the feeder head were analyzed in this paper. Firstly, the gas-solid two phase DEM model and coupled simulation method were studied. Then a 3D model of physical feeder and spread equation of the feeding surface were established. Finally, considering the surface data of the feeder head, the coupling simulation analysis was carried out with EDEM+Fluent software. As a research result, this paper recommends a curve equation of the feeding surface with different friction coefficients, deduces an equation for the transport quantity of the feeder head based on the transport and feeding quantity analysis, and presents an equation for rotate speed of the feeder head. The results provide an important guidance for the feeder head design.
