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 …

Abstract—The project deals with the design and analysis of bearing for the vibrating screen of capacity 100 tones per hour transmitting 20 B.H.P at a speed of 850 rpm. The design is based on the standard design procedure. In the present work by using the standard design procedure diameter of vibrating screen shaft has been designed.

Its high-frequency characteristics differentiate it from a normal vibrating screen. High-frequency vibrating screens usually operate at an inclined angle, traditionally varying between 0° and 25° and can go up to a maximum of 45°. They should operate with a low stroke and have a frequency ranging from 1500 to 9000 RPM.
