• Vibratory Screens General Kinematics

    Customer wanted to replace an existing vibrating screen due to frequent mechanical failure issues. Existing screen technology utilized the traditional brute force drive with large shafts, bearings, and motors. In the application, brute force screen technology typically had a useable life of around 1 year before mechanical failure occurred.

    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 Transmission refers to the fraction of desired particle that passes through the apertures in the screen.

    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 Transmission refers to the fraction of desired particle that passes through the apertures in the screen. At low frequency, screening efficiency is high but blinding is severe. Blinding will decrease as frequency increases but the particles will have difficulty going through the apertures. When designing a high frequency vibrating screen, an optimum point of frequency and amplitude must be chosen, depending on the specific applications. The separation efficiency is simply a measure of the amount of material removed by the screen compared to the theoretical amount that should have been removed. Screen efficiency can be obtained using different equation, which depends on whether the desired product is the oversize or undersize fraction from the screen. The screen efficiency based on the oversize (Eo) is given by: $${\displaystyle E_{o}={\frac {Q_{ms}(o)\;[1-M_{u}(o)]}{Q_{ms}(f)\;[1-M_{u}(f)]}}}$$The screen efficiency based on the undersize (Eu) is then given by: $${\displaystyle E_{u}={\frac {Q_{ms}(u)\;M_{u}(u)}{Q_{ms}(f)\;M_{u}(f)}}}$$where Qms(o) is the mass flow rate of solid in the screen overflow, Qms(f) is the mass flow rate of solid feed, Qms(u) is the mass flow rate of solid in the screen underflow, Mu(o) is the mass fraction of undersize in the overflow, Mu(f) is the mass fraction of undersize in the feed, Mu(u) is the mass fractio

    Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the
