Summary of maintenance methods for rotary kiln

Rotary kiln In the process of operation, with the extension of time, the parts will wear, thus reducing the reliability of the equipment in operation, and even affecting the output of rotary kiln. Therefore, it is necessary to take the opportunity of maintenance to restore. According to the maintenance workload, it can be divided into major repair, medium repair and minor repair. According to the use and maintenance of the rotary kiln, each user works out large, medium and small repair plans. Put it in minor repair and medium repair. The maintenance work can be carried out when the kiln is stopped to replace the kiln lining. Only the maintenance of the transmission device can be carried out after the bricklaying work is completed. But it should also be completed quickly in a short period of time (such as 8-12 hours). For overhaul, it will take a long time. At this time, it is necessary to replace all the loss parts of the kiln and adjust the whole equipment (such as: replacing the kiln shell section; replacing the big gear ring, wheel belt, supporting wheel, kiln head, kiln tail sealing parts, etc.), but it must be noted that before the planned shutdown, all the parts and tools to be replaced should be prepared to reduce the maintenance time.

 Rotary kiln

1. Wear of the ball of the supporting roller pad

In the operation process of rotary kiln, the wear of bearing seat ball is caused by the fracture of bearing bush. After the problem occurs, the traditional method can not be effectively repaired on site. Replacing new spare parts not only requires high cost, but also requires long-time shutdown for spare parts, which will cause heavy losses to enterprises.

2211f polymer metal repair material has super strong adhesion, excellent compressive strength and other comprehensive properties. Using meijiahua Fushi blue 2211f metal repair material, it can quickly repair the wear of tile seat ball without machining. In other words, there is no influence of welding thermal stress, repair thickness is also limited, at the same time, the metal material of the product does not have the yielding property, absorbing the impact vibration of the equipment, avoiding the possibility of wear again.

2. Cracks on the ball of supporting roller pad


Due to the accidental frost crack of the ball of the supporting wheel and the cast iron, the traditional method can not be used to repair it. Scrapping and replacement not only requires high cost, but also requires a long time of downtime for spare parts, which will cause heavy losses to enterprises.

2211f polymer metal repair material has excellent adhesion, excellent comprehensive mechanical properties, and good resistance to water, oil and chemical media. 2211f polymer metal repair material is used to repair the ball of supporting roller pad seat of rotary kiln, which saves a lot of downtime for enterprises, creates huge economic value, avoids scrapping and replacement, and optimizes the internal maintenance resources of the enterprise.

3. Repair of broken bearing block of supporting roller

During the operation of rotary kiln, the support roller bush seat is broken due to accident. After the problem occurs, the traditional method can not be effectively repaired. Replacing new spare parts not only requires high cost, but also requires a long time to stop waiting for spare parts, which will cause heavy losses to enterprises.

2211f polymer metal repair material has strong adhesion, excellent comprehensive mechanical properties, and good resistance to oil, water and chemical media. 2211f polymer metal repair material combined with traditional methods was used to repair the fracture of supporting roller bush seat of rotary kiln, which saved a lot of downtime for enterprises and created huge economic value, avoided scrapping and replacement, and optimized the internal maintenance resources of the enterprise.
