Vibrating Screen Working Principle

IntroductionNamingMechanismApplicationsPurposeCauseUseSpecificationsSafetyOperationAssessmentCriticismsAnalysisExampleAdvantagesConstructionTypesDesignThe simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel. A very erratic motion is developed when this wheel is rotated. You will find these simple screens in smaller operations and rock quarries where sizing isnt as critical. As the performance of this type of screen isnt good enough to meet the requirements of most mining operations two variations of this scre

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
