Comparisons on Self-Synchronizations of a Vibratory Screener with Considering Different Exciter Parameters

Self-synchronization principle is employed to achieve special processing tasks in ore milling industry, such as a vibratory screener. A multi-degree-of-freedom dynamical model of a vibratory screener is developed in the manuscript. The efforts of exciter’s mass eccentric moment, motor torque, rotating friction moment on the synchronizations of the motion of the vibratory screener, including transient motion, are investigated through numerical simulations. In particular, when a driven motor is shut down, the possible continuity of the self-synchronization motion of the screener, called synchronous transmission, at certain conditions is investigated
