Abstract

An agitator mill comprising a grinding vessel (3) which encloses a grinding area, a storage vessel (37) which contains grinding bodies (28), and a device (8) for feeding grinding bodies (28) from the storage vessel (37) into the grinding area. This device (8) essentially consists of a housing (11) attached to the grinding vessel (3) and a rotatable worm (13) situated therein. When the worm (13) is rotated, the grinding bodies (28) may be fed trouble-free as required into the grinding area, even if re-used grinding bodies (28) are concerned which have been worn out of true and have varied diameters.
