摘要
A grinding device including a rotor, mounted in rotational manner around an axle and having a plurality of blades extending radially relative to the axle. A sieve has a plurality of openings, with the sieve being mounted around the rotor so as to turn around the axle in the direction opposite the direction of rotation of the rotor. The rotor and sieve each has a height extending parallel to the axle and a width extending perpendicular to the axle wherein the width is between 1 mm and 20 mm. The rotation of the rotor and of the sieve is adjustable so as to reach a difference in circumferential speed between the rotor and the sieve between 100 m/s and 400 m/s, so as to reduce the average initial size of the crushed matter by a factor of 5 to 20.
