An agitator mill comprises an annular cylindrical exterior grinding chamber, which is defmed by an inner wall of a grinding receptacle and an outer wall of a rotor and an interior grinding chamber, which is defined by an inner wall of the rotor and an outer jacket of an interior stator. The grinding chambers are interconnected by a deflection chamber. Allocated to the interior stator is a separating device which comprises inner annular disks rotatingly drivably coupled with the rotor and outer annular disks non-rotarily connected to the interior stator.
