ABSTRACT:
A briquetting machine, primarily intended for briquetting fibrous plant material, includes a pair of rotatable wheels. Each wheel has die means towards its outer periphery and the die means define a circular row of pockets in which the material is received and compressed. During rotation the wheels come together to define a nip between the wheels. To provide for a varying volume of feed of material the wheels are relatively movable to vary the size of the pockets. Furthermore the die means include male and female, overlapping dies. In the bases of the dies are located ejector members which are urged outwards to eject compacted briquettes from the dies. To compress the material prior to entry into the dies there may be a precompression channel which converges toward its outlet end, opposite converging walls of the channels being formed of compression members which move towards one another and towards the outlet end.
