A screener of materials contains a cylindrical sieve, a brush rotor, a mechanism of loading and unloading windows. The brush rotor has drums with brushes located on them along the helix, in this case the drums are installed with possibility of rotation around their axes, at outlet ends of which the gears are located, which enter into external gearing with fixed wheel, mounted on the frame coaxially with the rotor. Technical result is the increase of productivity of the process.
