Abstract
The invention relates to a rotor for an agitating mill having a generally cylindrical rotor body, the outer wall of which defines an inner surface of a milling chamber, through which a feed material to be treated flows during operation of the agitating mill. A ceramic ring is arranged at the rotor end of the rotor body, the rotor end being arranged opposite the product inlet of the agitating mill. The invention also relates to an agitating mill comprising the rotor according to the invention, to the use of the rotor according to the invention in an agitating mill for producing dispersions, and to a method for producing the rotor.

A rotor for an agitating mill, comprising:
- a generally cylindrical rotor body, an outer wall of which defines an inner surface of a milling chamber through which a feed material to be treated flows during operation of the agitating mill, a ceramic ring arranged at a rotor end of the rotor body, wherein the rotor end is arranged opposite a product inlet of the agitating mill, wherein a surface of the ceramic ring forms a portion of the outer wall of the rotor forming the inner surface of the milling chamber, wherein the portion extends to milling tools arranged on the outer wall of the rotor, and the ceramic ring is secured by the milling tools against twisting and/or falling off.
An agitating mill comprising:
- a rotor, comprising:
- a generally cylindrical rotor body, an outer wall of which defines an inner surface of a milling chamber through which a feed material to be treated flows during operation of the agitating mill, a ceramic ring arranged at a rotor end of the rotor body, wherein the rotor end is arranged opposite a product inlet of the agitating mill, wherein a surface of the ceramic ring forms a portion of the outer wall of the rotor forming the inner surface of the milling chamber, wherein the portion extends to milling tools arranged on the outer wall of the rotor, and the ceramic ring is secured by the milling tools against twisting and/or falling off;
- a stator having a stator inner wall, wherein the rotor is arranged within the stator, a product feed and a product discharge,
- wherein a milling chamber is formed between the stator inner wall and the outer wall of the rotor, wherein feed material can be guided via the product feed into the milling chamber and via the product discharge out of the milling chamber.
