Abstract
A rotary feeder for transferring loose material, said rotary feeder having a housing, where a rotor transfers material from the feed channel of the housing into the discharge channel of the housing, the rotor having blades for transferring the material, and a counter blade is fixed in the housing of the rotary feeder between the blades of the rotor for cutting oversized pieces of material. A filler is arranged in the feed channel of the rotary feeder, to prevent the formation of a protrusion in the feed channel that would disturb the flow of the material formed by the counter blade, the edge of the filler adjacent to the counter blade being arranged to yield, and the filler is arranged to return to its initial position after the cutting operation.
