    TECHNICAL NOTES 4 VIBRATING SCREENS. 4-1 4.1 Classification Based on Sieving Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the important assumption in this approach is that the capacity of a screen is directly proportional to its. 4-2High-frequency vibrating screens Wikipedia,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.
