TLDR
In this paper, a systematic search of literature published during the last fifteen years was carried out and based on the analysis on these papers, these advanced design techniques and methods were summed up as three issues: the kinetic properties of the screen body by dynamic modeling, the optimal screening operational parameters by discrete element method and the dynamic design of the body by finite element method.About:

Pavlo Krot,Radoslaw Zimroz,Anna Michalak,Jacek Wodecki,Szymon Ogonowski,Michal Drozda,Marek Jach +6 more
TL;DR: The industrial vibrating screen is investigated on the 6-DOF (degree-of-freedom) dynamical model to reflect all linear and rotational components of spatial motion, and the model accounts for stochastic alpha-stable distributed impacts from the material.

An experimentally validated rubber shear spring model for vibrating flip-flow screens
TL;DR: In this paper, a variance-based global sensitivity analysis is applied to actually illustrate that the rubber shear spring is the most important component for the dynamics of Vibrating flip-flow screens.

Viscoelasticity of Rubber Springs Affects Vibration Characteristics of a Flip-Flow Screen With the High G Value
TL;DR: Results indicate that hysteretic damping of rubber springs can effectively solve the conflict between vibration strength and structural reliability of the flip-flow screen, since the low sensitivities of maximum stresses and the high sensitivity of accelerations to rubber springs damping are found.

Kinematics of a novel screen surface and parameter optimization for steam coal classification
TL;DR: In this paper, a rigid-flexible-coupled elastic screen surface (R-FCESS) was proposed for steam coal classification with 3-mm apertures, and the motion trajectory and vibration mode composition of regions on the R-FCess were investigated by vibration testing technology.
