ABSTRACT:
Apparatus for compacting powdered and fibrous raw materials to a pellet product, comprising a mixing chamber with an inlet, a driven mixing shaft coaxially with respect to the mixing cylinder and which is provided with radially projecting blades. A pelletizer is connected directly to the mixing cylinder, and comprises 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. The mixing shaft is designed as a cylinder, rotatable coaxially with respect to a fixed supporting shaft. The blades carried by the hollow mixing cylinder each preferable consist of two plate parts which have a common edge extending in the direction of displacement of material in the mixing chamber and at either side are positioned at an angle to the direction of the shaft and the direction of rotation of the drive is reversible, so that the mixing chamber at the end adjoining the pelletizer is provided with a closable discharge opening, the materials mixed and compacted can be either pelletized or discharged before pelletizing.
