sand vibration screens

A review on the advanced design techniques and methods of vibrating

For the traditional large vibrating screen, the method to reduce the blinding is to improve the vibration intensity of screen body. The vibration intensity (k = Aω 2 /cosα/9.8) depends on the vibration direction angle (α), amplitude (A) and frequency (ω) of the screen body [24]. During the whole screening process, a large amplitude at the ...
