Abstract
An agitator mill has an in each case annular cylindrical exterior grinding chamber and an interior grinding chamber, which are delimitated from each other by a cup-shaped agitator element, the interior grinding chamber and the exterior grinding chamber being connected with each other by bypasses formed in the agitator element for the return of auxiliary grinding bodies. In order to improve the grinding result and to increase the lifetime of the auxiliary grinding bodies or to be able to use even smaller auxiliary grinding bodies without their reaching a separator device arranged ahead of a grinding stock exit, carriers are arranged in the area of the bypasses at the inner casing of the agitator element and extend over a substantial part of the radial width of the interior grinding chamber and into it.
