Hollow shaft is an important part of the entire ball mill system, carrying the drive load of the entire barrel and grinding body of the ball mill, and performing continuous operation under the action of alternating stress, and the wear is relatively large. It can be said that the ball mill barrel is weaker. The links, therefore, are more difficult to control in terms of manufacturing quality.
In order to pursue greater profits, many companies are paying more and more attention to production costs, equipment operation rates, and operational reliability. After a long period of wear, the hollow shafts with poor quality will be cracked or even fractured, increasing the cost of maintenance. In case of serious downtime maintenance, the ball mill equipment ultimately has low production efficiency. From this we can see that the quality of the hollow shaft is directly related to the operating conditions of the ball mill and the economic benefits of the company.
The hollow shaft is the key part of the whole ball mill, and it is relatively high in terms of quality requirements. Due to its special structural shape, there will be an R zone, so no obvious casting defects are allowed after finishing. Some time ago, a cement clinker mill in Henan Province suffered from severe wear on the hollow shaft due to long-term use, resulting in downtime production, which in turn linked to Luoyang Yujie. Luoyang Yujie used a wealth of ball mill manufacturing experience to help the company create a new hollow shaft. No problems have occurred so far.
