ABSTRACT:
An apparatus is disclosed for converting feed material into granules under the application of pressure. The apparatus includes a conveyor screw arranged about an axis of rotation with at least one screw spiral, a rotationally symmetric working chamber arranged about the axis of rotation, which chamber is formed by two annular walls arranged at an axial distance from one another and by an annular perforated die. The annular wall has a central opening arranged coaxial to the axis of rotation into which the conveyor screw discharges in order to feed the working chamber with feed material. The apparatus also includes a pressure element that rotates about the axis of rotation and has at least one pressure arm, which extends from the axis of rotation toward the perforated die delivers the axially supplied feed material to the perforated die in the radial direction, and compacts it while doing so.
