Disclosed is a doser of a mounted centrifugal machine for broadcasting mineral fertilizers. It comprises a tank, in the bottom of which at least one discharge opening is provided, which has a depression as a part of a circle and is equipped with a measuring shutter to regulate cross-section thereof, which also has a depression of the same shape and size but of the opposite direction. The discharge opening and the shutter are made with additional depressions of similar shapes to the first ones. Centers of the circles of the depressions lie on the same radius of the bottom, and in the bottom of the tank an additional discharge opening with a shutter of similar shapes to the main one can be made. The angle between the radii of the disk, on which centers of the circles of the depressions of the discharge openings are arranged, exceeds 90°. |
