Raymond mill in the use of the process will inevitably encounter this or that kind of problem, especially with the material daily contact with the grinding roller and other accessories, the problem is also a normal phenomenon. So, how to deal with the fracture of the Raymond mill roller bolts?

If the Raymond mill in the use of the process of grinding roller bolts broken, will certainly affect the normal production. There is no other way to find the breakage, only to replace it. However, in normal times, we can take some effective measures to prevent this situation.

First of all, consider the strength of the threaded part of the bolt and the convenience of use, change the Raymond mill roller bolts from fine threads to ordinary threads, use double nut locking, and change the original twine sealing to sealing with the old transport tape, so that the transport tape plays a sealing role at the same time and also plays a cushioning role.

In addition, in the bolt fastening process, while tightening the nut in the mill with a sledgehammer to hit the oval head of the bolt, in order to make the oval head of the bolt head and the mill rollers screw holes with a good fit, and at the same time in the first time after tightening, Raymond mill shut down again, it is best to run a shift after tightening again, so that the bolt in operation due to contact caused by the loosening of the poor and the loosening caused by the thermal deformation to be able to tighten.
