Abstract: The aim of this article is to study the hydrodynamic vibration of knife refiners. Such vibration occurs due to hydrodynamic processes during the operation of the mill. A mathematical model is proposed that describes hydrodynamic vibration. The hydrodynamic force that excites the mill oscillations consists of the following main components: impact of the semi-finished product on the auger blades and headset knives; forward and reverse flow interactions; pressure on the knives of the headset. These forces depend on the design and operation of the mill. The error between theoretical and experimental studies does not exceed 20%. Vibration processes of hydrodynamic origin are mainly determined by the impact of the semi-finished product flow on the auger blades at the entrance to the mill. The proposed research technique can be used in other machines, for example, in centrifugal pumps.
