A feed mill contains a vertical screw mixer with cylindrical surface of housing and a hammer mill, including a housing, inside which a hammer rotor and edge deck are mounted, and loading and unloadingbranch pipes are located on its upper part, in this case, the loading branch pipe is connected with the internal cavity of reception bunker of the crusher. The hammer mill is of direct-flow grateless type, in which the internal cavity through the unloading branch pipe and the conduit for the pile is connected with the internal cavity of the upper part of the mixer. The crusher is equipped with dusty branch pipe, located adjacent between the loading and unloading branch pipes and connected through the air-and-coal conduit also with the internal cavity of the upper part of the mixer. The adjacent wall of unloading and air-and-coal branch pipes from the side of unloading pile is equipped with a adjusting shutter of the air flow and is made with possibility of displacement of the lower edge of adjusting shutter in the direction of apexes of the front angles of hammers at their upper vertical position. Conduits for the pile and the air-and-coal mixture are adjacent and are located tangentially with cylindrical surface of the housing of mixer.
