Mathematical Modeling and Numerical Simulation of the Functioning of Inertial Vibrating Screens in Resonant and Post-Resonant Regime

Inertial vibrating screens operating in resonance and post-resonance mode represent a class of screens that present a series of advantages: simple construction and maintenance, high flow rates, low energy consumption, low level of vibrations transmitted to the building in which they are located, high screening efficiency. Due to these advantages, they tend to replace all other types of screens. However, these cisterns are very sensitive to variations in the supply flow, therefore they must be equipped with electronic control devices and automatic control of the supply flow with mineral aggregates. The present paper presents a numerical simulation of the variation of the vibration amplitudes for different values of the material on the screen using the professional calculation program MATHCAD 14.
