<p>Apparatus for compacting powdered and fibrous raw materials to a pellet product, comprising a mixing chamber with an inlet, a driven hollow mixing cylinder rotatable coaxially with respect to the mixing chamber and which is provided with radially projecting blades. A pelletizer is connected directly to the mixing chamber, comprising a cylindrical mold coaxially inside a cylindrical jacket part and provided with radial holes, and inside which are arranged one or more freely rotatable pressure rollers as a result of which, when the apparatus is working, the compacted mixture is pressed through the holes, while the jacket part of the pelletizer is provided with an outlet for the compressed product. Preferably blades carried by the mixing cylinder each consist of two plate parts which have a common edge running in the direction of movement of the mixing chamber and at either side are positioned at an angle to the axial direction. The direction of rotation is reversible, the mixing chamber at the end adjoining the pelletizer being provided with a closable discharge opening. The materials mixed and compacted can be either pelletized or discharged before pelletizing.</p> |
