Repair: Using This Technology To Repair Worn Grinder Bearings Is Simple And Effective.

Repair: Using this technology to repair worn grinder bearings is simple and effective.

A coal pulverizer belonging to a steel plant has serious wear on the bearing on the transmission side. The main shaft diameter of the pulverizer is Φ200mm, and the bearing model used is /C3W·33. The wear depth has reached 0.5mm, and the wear width is 97mm. If this problem is not dealt with in time, the entire production line may be shut down, which will affect the daily coal crushing task.

How much trouble does bearing wear cause?

After the bearing position is worn, the gap between the bearing and the shaft becomes larger, which will produce strong vibration and abnormal noise during operation. This crusher is responsible for the key task of crushing coal in the steel plant. Once the machine is stopped for maintenance work, it will affect the crushing capacity of at least one hundred tons of coal every day, which will directly hinder the supply of raw materials for the subsequent iron-making process.

Why traditional repair methods cause headaches

In the past, there were two ways to solve the problem of bearing wear. One was to disassemble the shaft and transport it to an external factory, where it was cladded and then turned; or the other was to use brush plating or thermal spraying. As far as these methods are concerned, if the construction period is short, it will take three to five days, and if it is long, it will take more than a week. Moreover, the cost of disassembly, assembly and transportation of the equipment is high. At the same time, it is also easy to cause the shaft to deform due to thermal stress, thus laying a safety hazard for subsequent use.

How to operate Solei online repair technology

After receiving the repair report from the company, our technicians at Sole Industry first analyzed the equipment parameters and wear data, and applied the "Sole Tool Repair Process" on-site, using the unworn area on the shaft as a benchmark to apply carbon nanopolymer material, and then used the tooling to restore the original size of the bearing position. The entire process does not require disassembly of the spindle, and is completed directly in the original position of the equipment, avoiding the complexity of disassembly, assembly, and transportation.

Is this repair material reliable?

It is a high-strength carbon nanopolymer material with high wear resistance and good adhesion. After curing, it forms a repair layer that can be closely combined with the metal matrix. The dimensional accuracy of the repaired bearing position can be controlled within 0.01mm, which fully meets the matching requirements of the bearing and the shaft. We have used it many times before on coal crushers in other steel plants, and the effect is very stable. We have also used it many times on crushers in other steel plants before, and the effect is also very stable.

How long does on-site repair take?

From the initial preparation of the material to the curing stage, the entire repair process takes approximately six to eight hours. This material can be cured at room temperature without the need for heating and baking, and will not produce any stress or deformation. The equipment can return to normal operation on the day of repair, and the company does not need to arrange long-term shutdowns, which greatly reduces the amount of economic losses caused by shutdowns.

Which device scenarios is this technology suitable for?

It is not only applicable when the bearing position of the coal crusher is worn, but also can be used at the eccentric shaft bearing position of the jaw crusher. It can be used on various types of crushers, coal crushers, and sintering equipment. Whether the bearing position is worn, the bearing is sintered, or the journal is scratched, as long as the equipment parameters and drawings are given on site, we can develop a targeted online repair plan.
