Abstract

1. A pelletizing apparatus in which press rolls (11) disposed freely rotatable on a runner head (13) turn by the rotation of the runner head (13) relative to a die-plate (10) on the planar, punched die-plate (10), characterized in that the pelletizing apparatus is of two-stage design, in that two die-plates (10, 20) with the press rolls (11, 21) running thereon are disposed one above the other and in that the upper die-plate (20) has great passage holes (22) for loose strands of pellets of precrushed material, and that the lower die-plate (10) has smaller passage holes (12) which correspond to the dimensions and the compression of the pellets to be produced.
