Due to the large size of the beneficiation equipment ball mill, bearing is a key component of the ball mill, and the stability of its work will directly direct the production of the ball mill. From the development of traditional small ball mills to large-scale ball mills whose barrel diameter can reach 7 meters or more in recent days, the main bearings used include plain bearings, rolling bearings, dynamic pressure bearings, static and dynamic pressure bearings, and hydrostatic bearings. At present, hydrostatic bearings are widely used in large-scale energy-saving ball mills due to their high reliability, long service life, low energy consumption, and large bearing capacity. Ball mill whether it is stationary or rotating, is relying on the external pressure oil under the action of the bearing and the hollow shaft between the formation of a thick layer of oil film to achieve full liquid lubrication. The relationship between the lubrication state of the hydrostatic bearing and the pressure of the oil film and the rotation speed of the hollow shaft is very small. When the ball mill starts and works, the friction between the bearing shell and the hollow shaft is always in the state of pure liquid friction, and it is not easy to injure the bearing bush. In addition, the bearing capacity of the hydrostatic bearing is related to the hydraulic pressure. Increasing the oil pressure can increase the bearing capacity of the oil film. Since hydrostatic bearings work in a pure liquid lubrication state, their friction surfaces are not in direct contact with each other, resulting in minimal wear and long life, and can theoretically become an infinite life. With the trend of large-scale becoming a ball mill, the overall technological innovation of the ball mill is imminent. The so-called trend of the hero, the change of ball mill bearings is a bridge for the progress of the ball mill.
