Revisiting the models of vibration screening process

2014-10-10  Vibration screening is a process of great significance for granular materials processing. Notwithstanding the fact that the process has been studied with careful attention [1-4], its theory is by no means complete yet. Particularly, the relative role of stochastic and

Influence of vibration mode on the screening process

2013-1-1  The screening efficiency of the remaining section is null with no undersized particles being produced. The screening process gradually reaches a steady state when particles reach the discharge end of the screen and start to produce oversize material. The time to reach the stable state for the different vibration modes differs.

Influence of vibration mode on the screening process

A screening process is very dependable on design parameters such as the vibrator power, synchronisation of their drives, and oscillation frequency as well as the stiffness of supporting springs.

DEM Simulation of Spin Vibration Screening Process

This paper focus on the motion simulation and visualization of the material particles in the operation of the spin vibration screening using DEM(Discrete Element Method). Based on analysis of the simulation results, some conclusions are made which provide the theory basis in order to design the screen parameters reasonably.

Numerical simulation and analysis of vibration

2011-5-1  In order to find the best kinematical parameters (amplitude, frequency, vibrating direction angle), to improve efficiency and reduce the loss, vibration screening process simulation was carried out by EDEM software.

vibration parameters determines the screening performance [1, 2]. In order to improve the imperfect screening theory, the separation process is divided into four parts: looseness, stratification, percussion and penetration. Numerical modeling using DEM has been proven to be a useful tool to simulate the complex process of sieving phenomenon [3, 4].

Acoustic Induced Vibration Screening Assessment

The EI Guidelines were published to help minimise the risk of vibration induced fatigue of process piping, intended to be used by engineers with no prerequisite vibration knowledge. The EI method generates a Likelihood of Failure (LOF) score. The LOF is a form of scoring to be used for screening purposes.
