Along with the large scale has become a popular trend in the ball mill, the mill overall technical innovation has been imminent.The so-called heroes, ball mill bearing changes become a ladder of progress.

 

Due to the development of large ball mill, ball mill bearing as the key part, its working stability will directly whether the normal operation of ball mill.From the traditional small mill development to a cylinder diameter can reach 7 meters above the large ball mill, the main bearings are used mainly common sliding bearing, rolling bearing, dynamic pressure bearing, static and dynamic pressure bearing, static pressure bearing.

 

The hydrostatic bearing with high reliability, long service life, low energy consumption, large bearing capacity and other features, in large ball mill is widely used.Either stationary or rotating ball mill, is to rely on the external pressure oil under the effect of the bearing and hollow shaft between the formation of a thick layer of oil film to achieve full liquid

lubrication.Hydrostatic bearing lubrication and oil film pressure and the hollow shaft speed relationship is very small, starting when working with the ball mill, bearing bush and the hollow shaft is always in the pure liquid friction lubrication, easy bruising bush.Static pressure bearing capability of the bearing and lucrative and oil, increase oil pressure can improve the load capacity of oil film.As a result of hydrostatic bearing in the pure liquid lubrication condition, the friction surfaces without direct contact, so very small abrasion, long service life, can theoretically be infinite life.
