Claim 13:
14. An agitator ball mill having:
a grinding chamber which has a cylindrical wall;
a rotatably mounted agitator shaft which extends into the grinding chamber and on which at least one agitator element is arranged inside the grinding chamber;
an inlet configured to supply to the grinding chamber:
material to be ground; and
grinding bodies;

an outlet configured to remove ground material; and
an induction heater configured to heat the material to be ground, the induction heater comprising an inductor and a susceptor;, wherein:
the cylindrical wall of the grinding chamber consists of an electrically and magnetically non-conductive material;
the at least one agitator element:
comprises the susceptor of the induction heater, and
