Ball mill is a crushing machine commonly used in metallurgy, coal, mining, power generation, building materials and other industries. Spherical bearing has the name of "sliding bearing", under heavy load and high-speed rotation, the supporting role played by the spherical bearing is essential. Two stationary 120° spherical bearing hold a rotating cylinder and its contents. It is an indispensable accessory of ball mill.

The ball mill spherical bearing has a strong supporting effect, connecting the main bearing and the rotating cylinder of several hundred tons, which requires that the spherical bearing must have a high compressive strength, so the material of the spherical bearing (bearing body) is mostly HT200 or ZG270 -500.

The main bearing bush of the ball mill is an automatic self-aligning spherical bearing. In order to make the spherical bearing and the bearing seat uniformly stressed, it is necessary to scrape the spherical bearing back and the concave spherical surface of the seat, and apply red powder to the concave spherical surface of the seat. The method of grinding the bearing back and concave spherical surface is to observe the distribution of contact points on the concave spherical surface until uniformly distributed.
