Flip-flow screen with crankshaft-link structure (FFSCLS) is effective for screening of high-water and fine materials. In this paper, a dynamic model governing the vibration and mechanical characteristics of the FFSCLS is proposed. In addition, the motion trajectory and vibration data of the FFSCLS were investigated by MATLAB/Simulink method. The results show that the MATLAB/Simulink method can fully describe the vibration characteristics of the FFSCLS with the maximum deviation within 6.71 % between experiment results. The mechanical characteristics of the FFSCLS were systematically studied by automatic dynamic simulation analysis using the ADMAS software. The MBD simulation results indicated that the resultant forces of the inner and outer screen boxes are always equal to 0. Moreover, the rotational speed of the crankshaft, the stiffness coefficient of the guild springs and rubber springs determined the mechanical characteristics of the flip-flow screen, and these parameters should be optimized. This work is helpful for the understanding of the combined effects of parameters and provides essential references for optimal design and efficient operation of a flip-flow screen with crank-link structure.

Vibrating flip-flow screens have been widely used in the mineral processing industry. As the key components, flip-flow screen panels strongly affect the dynamics of vibrating flip-flow screens. However, there is no systematic research into this problem. In this study, the dynamic characteristics of flip-flow screen panel are identified by the finite element analysis. Furthermore, a nonlinear coupling dynamic model of vibrating flip-flow screens that considers the effects of flip-flow screen panels is proposed, and the analytical and numerical solutions of its governing equation are deduced via the equivalent linearization method and the time marching method. Also, experimental results show that the proposed model describes the movements of vibrating flip-flow screens more accurately than the classical mechanical model which does not consider flip-flow screen panels. Finally, the effects of the screen panel's parameters, such as the slack length and the stiffness, on the dynamics of vibrating flip-flow screens are investigated.
