The apparatus for continuous kinematic high frequency treatment of a substance or a mixture of substances is provided with two respective comminution member rings both on the stator and on the rotor. At least the outermost comminution member ring and generally the three outermost comminution member rings are provided with narrow slots having a width of less than 1 mm, preferably less than 0.5 mm, which are closed at the free end of said rings. The closed slots are manufactured by means of a carbon dioxide laser device. In the process, first the comminution members, which are provided with holding means, are manufactured and the slots are cut by the laser device, and then the two holding means of the stator and the two holding means of the rotor are welded together. By providing these narrow slots, a finer mixture with higher efficiency is obtained.
