The invention relates to the screens. A screen includes a frame installed on elastic supports, a sieve secured on the frame in the form of sifting sections connected between them and located at different angles to the horizon, a vibration exciter and a device for loading of material. It is equipped with pivot bearings located between elastic supports with displacement along the horizontal of their centers from the line of joining the sifting sections of sieve, in this case the projection of a part of sifting surface on the horizontal plane located from the center of pivot bearings toward the side of loading is lower than the projection on the same plane of remaining part of the sifting surface.
