Ball mill is the key equipment for crushing materials after they are crushed, which is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries. In the process of long-term use, the ball mill will have shaft head wear problems due to a variety of reasons, so let's take a look at what causes the shaft head of the ball mill to wear out!
normal fatigue wear of metals;
Coordination relationship issues;
Installation problems, the installation position of the bearing can not be well controlled or the clearance of the bearing can not be effectively controlled during the installation process, resulting in the bearing can not be in an optimal state during operation, and then the running resistance increases, the temperature increases, and the torque acts more on the mating surface, resulting in the relative movement of the inner ring of the bearing and the surface of the shaft, resulting in the wear of the shaft;
Operation and maintenance, including poor lubrication of bearings, high operating temperature due to clogging of cooling systems, loosening of fastening devices, etc.
If the shaft head of the ball mill is worn, if it is not repaired in time, it may affect the safe and stable operation of the equipment.
In order to ensure a good repair effect and start operation in a short time, the company chose to use Soray carbon nanopolymer material technology to repair the shaft head wear problem of the ball mill. Our engineers have formulated a targeted maintenance plan for the wear of the shaft head of the ball mill after a detailed understanding, and completed the maintenance of the shaft head of the ball mill with quality and quantity, the specific process is as follows:
Surface degreasing and grinding of the parts to be repaired;
Proportionally blend the Soray carbon nanopolymer material and apply it to the area to be repaired;
The material is cured, excess material is removed, and the size of the repaired material is measured;
Reload.
