ABSTRACT:
In continuous operation of agitator mills, in particular when processing abrasive products, which operate with grinding bodies (35) in a grinding area, worn grinding bodies must be replaced. A grinding body feed device (9) which can be used for grinding bodies (35) of different shape and size comprises an intermediate chamber (43) from which the grinding bodies (35) pass from a storage vessel (33) into the grinding area without any material being ground getting into the storage vessel (33). The intermediate chamber (43) can be shut off at its inlet and its outlet in each case by means of a valve (19, 41; 47, 49), one of which is always closed during the introduction of grinding bodies (35) into a product supply pipe (45) leading to the grinding area.
