The Vibrating screens have accuracy of sizing, increased capacity per square metre and low maintenance cost per ton of material handled. Principle and Operation of the Vibrating Screen. In the case of a vibrating screen, the vibrations are given to the screen to effect the separation of solid particles into two size fractions.
In some high frequency vibrating screens the flow rate of the feed can be controlled, this is proportional to the 'popcorn effect'; if the flow rate lowers, the effect is also decreased. Limitations of the high frequency vibrating screen are that the fine screens are very fragile and are susceptible to becoming blocked very easily.
