ABSTRACT:
An agitator mill comprises an annular cylindrical exterior grinding chamber, which is defined by an interior 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 connected with each other by a deflection chamber. The exterior grinding chamber is equipped with agitator elements, whereas the interior grinding chamber is smooth-walled, free from agitator elements. The cross-sectional surface of the exterior grinding chamber considerably exceeds the cross-sectional surface of the interior grinding chamber.
