In this diagram, a large group of people accept the offer of a screening test. The sieve represents the screening test and most people pass through it. This means they have a low chance of having the condition screened for. The people left in the sieve have a higher chance of having the condition. A further investigation is then offered to them. Identification through this process can show that they have the condition screened for. The person may need further confirmator
  • 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
