ABSTRACT:
A press of the kind for the preparation of pellets of cattle feed or other pelletizable 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 frusto-conical surfaces, there being wedge means on one part engagable with ramp means on the other part such that transmission of torque from the driving rim to the die causes said ramp and wedge means to cooperate to bring said mating surfaces into pressurized engagement.
