### 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
