The ball mill head  and ball mill trunnion are damaged during use, which will affect the use of ball mill equipment. China large casting steel manufacturers summarize the following points according to the problems that customers often encounter:

1. The ball mill head  and ball mill trunnion. If there is a large error, it will easily cause a crack or depth of dentation in the area.

2. When the axial part of the ball mill is cracking, the defect will be extended to both ends, and in severe cases, it will be scrapped directly.

3. If the ball mill head wear more than 50 % during the use of the ball mill, it is directly scrapped.

During the long -term use of the ball mill head, the end cover will be worn due to material fatigue; some materials with a small amount of particles will also enter the middle of the end cover content and the spiral cylinder, resulting in severe inner holes. If the operation is improper, it will increase the degree of wear of the ball mill end cover. The above is the common wear of the end cover of the ball mill with Henan cast steel manufacturers. Therefore, once the end cover is found, it must be processed immediately, otherwise it will affect the operation of the ball mill.

There is also a corresponding method for the repair of the end cover. You can directly remove the end cover for driving treatment. There are also cracks in the appearance of some parts. Be sure to find the crack extend in which direction, and determine that the end point is using the turning. Some steel casting manufacturers will use welding supplements to handle the neck.
