The machine has a cutting component(11) rotating in a chamber(10), a feed screw(1) with its rotational axis(3) coinciding with the rotational axis of the cutting component and its delivery end section adjacent to the cutting component, and an outer jacket(6) connected to the cutting chamber and enclosing the feed screw, at least in the region of the delivery end section. Stationary cutting arms(9) extend radially from the outer jacket towards the rotational axis, and radially disposed blades(12) rotate inside the chamber.
