Vibration screen contains cylindrical housing mounted on the support with the help of elastic elements and connected with the vibration drive, in upper part of said housing the loading hole is executed, surface of sifting located inside the cylindrical housing and diaphragm located under it, said diaphragm is executed in the form of a truncated cone directed by apex downward, in lower base of which an opening is executed, and also the branch pipes of unloading from the surface of sifting. It additionally contains the second surface of sifting mounted under said diaphragm and has the size of mesh equal to the size of mesh of the upper surface of sifting, it contains two cone-shaped sections directed by apexes upward and mounted under each surface siftings. In this case cone-shaped section mounted under the upper surface of sifting is located above the diaphragm. Furthermore, one of the branch pipes of unloading from the surface of sifting is executed in the form of a pipe connecting the cavity located above the upper surface of sifting, with the cavity formed between the diaphragm andcone-shaped section located above it. It contains an additional branch pipe of unloading from under the surface of sifting mounted between the upper surface of sifting and the cone-shaped section located under it.
