A pellet machine includes a hopper feeding a pair of inter-locking counter-rotating dies. Feeders convey material from the hopper to pre-compression rollers on the dies. A mat of the material is rotated on the dies into a nip between the pair of dies. Teeth on each die are in opposed facing relation to the teeth on the opposite die as the teeth rotate into the convergence area in the nip. Pellet forming chambers are inter-leaved between the teeth on both dies. The teeth are offset between the two dies so that the teeth act as plungers driving and compressing the material mat into and through the chambers as the teeth on each die drive into the opposed facing depression between the teeth on the opposite die. The material is driven through the chambers to extrude into the interiors of the dies.
