A press of the kind for the preparation of pellets of cattle feed or other pelletisable material and comprising an annular die having a plurality of radial bores therein, which is mounted on a driving rim for rotation around a stationary support fitted with a number of pressure rollers, each freely rotatable on a stationary shaft and in closely spaced relationship with the interior surface of the die, the arrangement being such that material fed into the interior of the die is forced through the bores therein by the action of said pressure rollers, characterized in that the die and driving rim therefor are provided with complementary circumferential mating male and female conical surfaces, there being a plurality of circumferentially spaced links each of which is arranged to be pivotally connected at its opposed ends to the driving rim and die respectively such that transmission of torque from the driving rim to the die causes pivoting movement of said links to bring said mating surfaces into pressurised engagement. |
