· Abstract. In the single-excitation-motor inertial flip-flow screen, the vibration phase difference is difficult to maintain at the ideal angle of 180° for two screen frames, which results in the low screening efficiency. To solve this problem, a flip-flow screen driven by double excitation motors is established, together with its control system.
