1. An agitator mill comprising:
a grinding container limiting a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein around a horizontal axis and has a plurality of grinding disks connected thereto, the grinding disks are spaced apart from one another in a direction of the horizontal axis and cause the grinding bodies to move,
wherein each grinding disk has slits or apertures, wherein adjacent ones of the grinding disks are arranged on the agitator shaft so that a ratio of a grinding chamber length to a radial grinding chamber height is greater than or equal to 2:3, and so that a radial distance between an outer jacket surface of the grinding disks and an inner wall of the grinding container is more than 20% of the radial grinding chamber height,
wherein the agitator shaft forms a rotor disk on an end of the agitator shaft, the rotor disk comprises rotor bars protruding from the rotor disk in a longitudinal direction of the agitator shaft and forming openings between adjacent ones of the rotor bars, and the rotor disk further comprises recesses in fluid communication with the openings, wherein the recesses are smaller than the openings at least in a circumferential direction of the rotor disk.
