Disc mill

A disk mill comprising two grindings disks each formed as a ring with a central hole, with the disks being disposed so as to be essentially parallel to one another, and rotatable with respect to one another about a common axis which extends through the central holes of the disks, and which comprise:

• first working surfaces in an inner area which are directed towards one another, are spaced apart from one another thereby forming a working space in the area of the hole, run conically towards one another in the outwards direction, and narrow the working space;
• and
• second working surfaces formed in an outer edge section so as to be parallel to one another and with at least slight spacing from one another, wherein the first working surfaces as well as the second working surfaces are provided with straight cutting teeth, wherein the cutting teeth have an approximately saw-tooth cross section, wherein the cutting teeth of the first and second working surfaces of the same grinding disk run in the same direction obliquely to the radial direction, and wherein the cutting teeth of the second working surfaces are inclined more sharply than the cutting teeth of the first working surfaces.
