Abstract
An agitator mill, in particular an agitator bead mill having a mill housing, in which an agitator shaft, preferably bearing agitator elements, circulates in such a way that a grinding chamber is configured between the agitator shaft and the mill housing, and into the chamber the grist is fed, transported by a fluid carrier substance, as a rule in the form of a suspension, wherein the grinding chamber is partially filled with grinding media, which are set in motion by the circulating agitator shaft and thereby the grist, carried through the grinding chamber by a fluid carrier substance, is crushed, wherein the grist, transported by the fluid carrier substance, is discharged together with the carrier substance through a sieve, which retains grinding media that arrive as far as the area of the sieve, wherein the sieve consists of several sieve elements arranged one after the other along the longitudinal axis of the agitator mill, the sieve elements being penetrated in parallel manner, with their surfaces flowing from the grinding chamber, and extend diagonally or radially to the axis, around which the agitator shaft circulates.
