1. the neck position of the end cover of the ball mill and the middle of the hollow shaft, if there is a relatively large error, it will easily cause cracks or deep dents in the part.

2. When the axial part of the ball mill is cracked, the defect will extend to both ends, and in serious cases it will be scrapped directly.

3, the ball mill end cover in the process of use if the amount of wear has exceeded 50%, it is directly scrapped.

In the process of long-term use, the end cover of the ball mill will wear because of material fatigue; Some small particles of material will also enter the middle of the end cover content and the spiral cylinder, resulting in serious wear of the inner hole; When the end cover of the ball mill needs to be maintained, if the operation is improper, it will increase the wear degree of the end cover. The above is the common wear causes of the end cover of the ball mill introduced to you by Henan Steel Casting factory, so once the end cover is found to be worn, it must be treated immediately, otherwise it will affect the operation of the ball mill.
