The device for the continuous kinematic high frequency treatment of a material or material mixture has in each case two comminuting element rings (6, 7; 10, 11) both on the stator (2) and on the rotor (3). At least the outermost comminuting element ring (6), in general the three outermost comminuting element rings (6, 7; 10) have narrow slots (14, 15; 17) with a width of less than 1 mm, preferably to less than 0.5 mm which are closed towards the free end (13) of the rings. …<??>The closed slots are produced with a CO2 laser device. Firstly, the comminuting elements provided with holder pieces (4, 5; 8, 9) are produced and the slots are cut out with the laser device and subsequently the two holder pieces (4, 5) of the stator and the two holder pieces (8, 9) of the rotor are welded to one another. …<??>By producing these narrow slots, a finer mixture with a higher yield can be obtained. …<IMAGE>… |
