During use vertical roller mill in slag power grinding, there will often appear rollers, disc liner wearing, roller bearing wearing, gear chamber leakage and other common problems, due to poor working conditions. And today, I want to tell you some troubleshooting methods for dealing with the vertical roller mill problems.

Vertical roller mill roll body and liner wear during use, the gap between the body and will cause wear liner intensified, combined with hot air and cement particles on the mating surfaces of constant erosion, resulting in the generation of a trench, and impact collision occurred between the body and the liner, the liner making serious cracks or fracture, damage to the machine, especially damage to the gear unit, resulting in a vicious incident. Once this kind of problem occurs, general repair methods are difficult to solve, replace costly.


Vertical roller mill roller assembly requirements more stringent bearing companies generally use dry ice cooled bearing on the way the assembly. Once a gap occurs between the bearing and the bearing chamber, it will affect the normal operation of the bearing, resulting in bearing fever, severe burning phenomenon will cause bearing; vertical mill reducer leakage not only affect the appearance of the machine, and waste oil, to maintenance of equipment maintenance caused great trouble.

These problems are generally difficult process for welding repair resolve bad soldering iron and easy to parts caused by welding more serious secondary damage, the replacement cost of a long high time. Western countries currently use more polymer composites scene solve this kind of problem. The compressive strength of the material unique, good plastic deformation and superior machining performance, when repairing these problems reflect the fast, convenient, durable features, enterprises save a lot of valuable downtime, and allows businesses to learn repair and maintenance of a new technology, in the face of similar problems again, companies can independently solve the first time.
