However, when increases to 1000 r/min, decreases because larger vibration frequency can lead to larger penetration probability of particles whose size is larger than separation size. Optimum vibration amplitude and vibration frequency are 3.5 mm and 960 r/min, respectively. Figure 7 Effect of vibration amplitude on the sieving efficiency.

High-frequency vibrating screens Wikipedia

The purpose of the vibrating screen is that particles are introduced to the gaps in the screens repeatedly. The frequency of the screen must be high enough so that it prevents the particles from blocking the apertures and the maximum height of the particle trajectory should occur when the screen surface is at its lowest point. Based on the principle, there is an optimum frequency and amplitude of vibration

Discrete element modelling of vibrating screens

01/06/2018 In order to examine the effects of screen vibration amplitude on the screening performance and related factors, four simulations at vibration amplitudes of 3, 4, 5 and 6 mm have been performed by keeping the other parameters constant. Physical properties of the feed as well as the screen motion are given in Table 1. In the simulations, the feed flow rate, screen inclination, vibration frequency and vibration
