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.

Abstract: A separator system for separating grinding bodies and ground material in an agitator mill wherein stationary and moveable or oscillating separator members in a grinding chamber define a variable gap which narrows when a moveable separator member moves against the flow of ground material.

Abstract: An agitator mill with diluting medium injected into the grinding container at different spacings from the inlet of the container with dosing devices connected to dosing pumps, which dosing pumps are operated in synchronization with a charging pump via a common jackshaft whereby adjustment of the amounts of diluting liquid reaching the grinding space is made in accordance with the amount of material to be ground flowing through the grinding container.
