The paper considers automatic balancing devices for knife refiner rotors which rotate in a two-phase or three-phase medium. The total imbalance of the mill rotor consists of mechanical, hydraulic and hydrodynamic components. The main component is mechanical imbalance, which changes during operation due to uneven wear of the headset. It is recommended to use automatic rotor balancing devices in the designs of these machines. These devices allow compensating for the mechanical component of the rotor imbalance without stopping the mill. A mathematical model and designs of automatic balancing devices for mill rotors have been developed. The proposed calculation method and design of automatic rotor balancing devices can be used in other machines, for example, in centrifugal pumps.
