The invention relates to the agricultural machinery industry, in particular to feed preparation devices. The feed preparation extruder comprises a body (1), wherein it is placed a pressing auger (2), equipped with a conic tip (6) with a cylindrical part (7) at its base, a cover (4) with conic inner surface and a central hole, and a former (5) with a conic hole at the inlet and a cylindrical one at the outlet. The conic surfaces of the auger tip (6), of the cover (4) and of the hole of the former (5) are made with equal cone angle. The former (5) is made in the form of adjusting screw, installed into the central hole of the cover (4). The conic tip (6) of the auger is installed with the possibility of controlling its axial position about the auger (2), and onto its cylindrical part (7) there are made slots for gripping during control. The result consists in simplifying the extruder construction, in simplifying its maintenance and in the possibility of setting in the operation process.
