Abstract

An agitator mill for treating free-flowing grinding stock has a grinding receptacle and an interior stator disposed therein. A rotatably drivable annular cylindrical rotor is disposed between the interior stator and the receptacle wall, with a grinding chamber being defined between said rotor and the receptacle wall. A grinding-stock discharge conduit is formed between the rotor and the interior stator (22) which is connected to the grinding chamber by means of a deflection conduit. Devices are provided for preventing the carry-over of auxiliary grinding bodies from the grinding chamber into the grinding-stock discharge conduit.
