ABSTRACT:
An agitator mill for flowable mill charge grinding, has a fixed, outer, cylindrical grinding container, to which is coaxially fitted in spaced manner a cylindrical inner stator. A rotary driven, cup-shaped rotor is positioned coaxially to the grinding container and engages in the grinding area formed between the grinding container and the inner stator, so that the grinding area is subdivided into an outer grinding area and an inner grinding area, the grinding areas being interconnected hydraulically by means of a connecting area. A discharge device located within the inner stator is connected in the flow direction to the inner grinding area. A rotary, cylindrical separating screen is positioned coaxially to the rotor between the end of the inner grinding area and the discharge device. In order to ensure a correct operation of the agitator mill with relatively low constructional costs, the separating screen is fitted to the rotor and sealed with respect to the inner stator by means of a seal, particularly a slip ring seal.
