Springs are critical components in mining vibrating screen elastic supports. However, long-term alternating loads are likely to lead to spring failures, likely resulting in structural damages to the vibrating screen and resulting in a lower separation efficiency. Proper dynamic models provide a basis for spring failure diagnosis. In this paper, a six …

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 vibrating screen, gravity and ...

Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
