Abstract

An agitator mill including a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein around a horizontal axis and which supports several grinding disks, which are connected thereto and which are spaced apart from one another in the direction of the horizontal axis and which move the grinding bodies, wherein grinding disks preferably in each case have slits or apertures, wherein adjacent grinding disks are arranged on the agitator shaft so that the ratio of the grinding chamber length to the radial grinding chamber height is greater than or equal to 2:3, and that the radial distance between the outer jacket surface of the grinding disks and the inner wall of the grinding container limiting the grinding chamber is more than 20% of the radial grinding chamber height.
