High-frequency vibrating screens Wikipedia

Limitations of the high frequency vibrating screen are that the fine screens are very fragile and are susceptible to becoming blocked very easily. Over time the separation efficiency will drop and the screen will need to be replaced. An alternative to the high frequency vibrating screens is the rotary sifter.
