Working Principle of Vibratory Screener | INDPRO Engineers
Vibratory Screening is the process of taking particulate material and separating it into multiple grades by particle size. This method of particle separation uses gravity, motion, and mesh screens or sieves to accomplish the separation.
The screener is mechanically vibrated in a controlled manner to allow the particles to flow across the screen and outward in a spiral pattern. The oversize particles flow across the screen and are discharged through a spout. The smaller particles fall through the mesh screen(s) and continue to spiral until they are discharged.
Operational Vibratory Screener
The vibratory screener uses a rotating eccentric motion generator that provides a circular motion along a vertical plane. High frequency with small amplitude (stroke) provides maximum screening efficiency.
When operating (turning) in the forward direction (with the flow), all the material moves down by gravity. With-flow rotation is used for efficiency rather than high efficiency, such as scaling operations. When operating counter flow, the vibrator operates (turns) in a direction that is opposite to the normal downward flow of the particulate material. With counter flow, larger particles move down the screen faster, and smaller particles remain in contact with the screen for a longer period of time, increasing the screening efficiency.
In the case of a vibrating screen, the material to be separated is fed to the top screen and simultaneously the screens are vibrated either electrically or mechanically at a frequency of 1000 to 3500 per minute. Due to vibrations, the particles on the screen are kept moving and due to the inclination given to the screens, the oversize material travels along the screen and is collected separately. The undersized material passes through the screens and is collected. Four fractions are obtained with a three-deck screen.
