Basic concepts of vibrating screens: What they are, what ...

Vibration frequency in vibrating screens. As a general rule for large classifications, low frequencies and large vibration amplitudes are preferable and for fine classifications high frequencies and small amplitudes. In other words, if the particle is large, a slow and wide movement is better in which the particle gives few jumps but large and if it is small it is better than many jumps but smaller. It is a

METHOD OF DETERMINATION OF VIBRATING SCREENS'

Traditional designs of vibrating screens have a uniform field of amplitude over the entire surface of the sorting surface generally. Thus, the oscillation amplitude has the same value over the entire sieving surface, or a constant value in each point of the sieving surface. This phenomenon poses a number of problems of sorting of bulk materials, which, ultimately, do not allow to obtain ...
