Nonlinear Model of Vibrating Screen to Determine

The deck is supported by springs. Figure 2 shows the model of vibrating screen considered in this study, where is the mass of the vibrating screen when in operation; is the moment of inertia of the center of mass of the 3.2 Dynamic Analysis of Vibrating Screen. Since the vibrating screen is an inertial screen, during the vibration process, the force generated by the eccentric mass of the exciter is mainly driven; that is, the inertial force plays a leading role, and the spring restoring force and the damping force are negligible [].Therefore, in the dynamic analysis of the Structural Analysis and Optimization Design of Linear Vibrating Screen

The Nonlinear Dynamic Behavior of a Particle on a Vibrating Screen

Hence, the particle dynamic behavior of a circular vibrating screen and linear vibrating screen in the normal direction is the same with the same amplitude in the normal direction. Figure 2 a shows the particles dropping from three heights (0.3, 0.301, and 0.302 m) under f = 16 Hz, and A = 4 × 10 −3 m.Predictive maintenance is increasingly popular in many branches, as well as in the mining industry; however, there is a lack of spectacular examples of its practice efficiency.
