Precautions for setting bearings during the installation of ball mills

Precautions for setting bearings during the installation of ball mills

We all know that the main bearing of a ball mill is a very important component, which supports the entire cylinder of the ball mill and plays a significant role in reducing the 

friction coefficient of the equipment during movement, narrowing the displacement difference of the ball mill relative to each other, and stabilizing the position of the ball 

mill. In addition, the main bearings of the ball mill also have many functions. Therefore, as an article series that provides a deep and systematic introduction to the installa

tion of the ball mill, some rules for setting the main bearings of the ball mill cannot be ignored. It is a necessary part of the installation and an important musical element 

in this installation prelude. Given the crucial role of the main bearings in ball mills,

Today we will discuss some rule settings for the main bearings of the ball mill. People who often engage in mechanical production understand the enormous effectiveness 

of the main bearings of ball mills in the entire operation process of the equipment. When we introduced some rules for the overall setting of ball mills, we mentioned that 

people do not pay enough attention to the setting of ball mills, and only stay in the maintenance and upkeep period for related operations. Similarly, for the main bearings 

of ball mills, people only pay attention to them after production, and only think about and solve problems after they occur, which delays the production process and incre

ases production costs.

We have summarized and organized the relevant rules for the setting of the main bearings. We hope that everyone can pay attention to and value the equipment of the ball 

mill from the very beginning, so that the operability in the production process can be more perfect.

1. Some numerical standards for main bearings. The numerical standards for the main bearings are determined based on the drawings, and these ball mill standards

   themselves are very strict, so they must be strictly controlled during actual operation. Specific precautions include: the distance error between the centerlines of the

   two bearings of the ball mill should be within 1mm; The elevation error of the base of the main bearing is within 0.5mm, and the discharge end must be lower than

   the feed end; The contact gap between the bearing and the bearing base shall not exceed 0.1mm, and the edge length of the non-contact part shall not exceed 100mm, ensuring that the sum of all lengths is less than 1/4 of the total circumference.

   
   

   
   

2. Some settings of the bearing shell. The water channel of the ball mill bearing must be clean, and we should continuously inspect and test the pressure of the bearing

   to ensure the sealing tightness of each connection.

   
   

3. Some settings for lubrication of main bearings. Lubricant should be applied to the contact area between the main bearing and the base to ensure the flexible rotation of

   the bearing. At the same time, all components that require lubrication should be cleaned thoroughly, and the connection at the joint should be tight. We have provided

   some requirements for the setting of the main bearings of the ball mill. Although the knowledge may be a bit weak, we hope that this knowledge can be combined with

   everyone's actual production to make the operation of the ball mill more complete and perfect.
