# Research on the characteristics of spatial 6-degree-of-freedom linear inclined vibrating screen

## TL;DR

This study analyzes how different movements of a vibrating screen affect the screening process, identifying how each movement influences material dispersion and flow.

## Contribution

A novel 6-degree-of-freedom dynamic model of a linear inclined vibrating screen is established and experimentally validated.

## Key findings

- X-direction translation promotes mixture dispersion.
- Y-direction translation increases mixture velocity toward the outlet.
- Z-direction rotation may cause mixture blockage.

## Abstract

This article takes the linear inclined vibrating screen (TLIVS) as the research object, establishes a spatial 6-degree-of-freedom dynamic model of TLIVS, and verifies the correctness of the established model through comparison between real experiments and simulation experiments. Steady-state response of TLIVS is solved by numerical analysis method, The influence of each degree of freedom acting separately on the screening process of TLIVS was explored using the discrete element method. The results indicate that x-direction translation movement mainly promotes the dispersion of the mixture, and y-direction translation movement mainly increases the velocity of the mixture towards the outlet. z-direction translation movement mainly causes the mixture to stratify. Rotation in the x-direction accumulates the mixture in the middle of the screen surface, rotation in the y-direction helps to disperse the material at the inlet, and rotation in the z-direction may cause blockage of the mixture.
