Abstract
A method for determining parameters of a high-frequency vibrating mill with three grinding drums is disclosed. The mathematic modeling is established by applying the average parameter method and transfer function method; the synchronization-stability capability coefficient curve, and the dimensionless coupling torque maximum value diagram of the system are obtained by the characteristic analysis of synchronization and stability. Finally, the curves of rotational velocity of motors, displacements of mass bodies, and phase difference between exciters are obtained by the simulation, and the correctness of the method is verified by the comparison of characteristic analysis and simulation. The parameters of the high-frequency vibrating mill of the present invention can lower the technical requirements of exciters, reduce the loss of the exciters, increase the service life of the mill.
