A vibrating screen comprises a box with a screening surface located through elastic elements on a support frame, and a vibratory drive. The vibratory drive comprises two kinematically non-connected self-synchronized inertial vibration exciters installed on opposite sides of the screen box, in perpendicular to the transverse axis, while the axes of the vibration exciter are turned in opposite directions at the same angle ( relative to the vertical axis of the center of mass of the box, and rigidity of the elastic elements in the longitudinal section is for 2-3 times larger than in the transverse section.
