Abstract:  Aiming at the electromagnetic vibrating feeder on the difficulty of adjustment in transferring different materials with it. The theories of material slide and throwing were applied in the design and adjustment. A dynamic model of the electromagnetic vibrating feeder was analyzed, and a method choosing an appropriate working point based on amplitude was put forward. On the basis of the analysis of acting forces of the material, the relationships between the amplitude and the way of material movement were mainly studied, an equation of material movement was established, and the relationships between the amplitude and the average speed of the three materialsupplying ways of forward slide, opposite slide, and throwing were obtained by solution of the equation. The research  results show that the amplitude of electromagnetic vibration feeder not only decides the movement ways of the material, but also has a great effect on the delivering speed.
