Rotary kiln equipment is a large-scale mechanical equipment. In order to ensure the long-term safe operation of the equipment during operation, regular maintenance of the equipment is required. The primary task of the maintenance of rotary kiln equipment is to maintain the "straight and round" of the kiln body and the stability of axial movement. The most important task is to adjust the tug correctly. How to adjust it correctly?

1. The basic principle of adjusting the supporting roller:

(1) Adjust the supporting roller so that the center line of the kiln body is a straight line. The kiln body of the rotary kiln is supported on the multi-gear supporting roller through tires. When the size of the supporting parts remains unchanged, the position of the kiln body is the supporting wheel. The location is ok. When the rotary kiln is in use, the position of the supporting roller must be adjusted frequently to ensure that the center line of the kiln body is in a straight line.

(2) Adjust the supporting rollers to make the kiln body move normally. During the operation of the rotary kiln, in order to make the surface of the supporting rollers and tyres wear evenly, the kiln body should be continuously moved axially between the upper and lower retaining wheels (called swimming). verb: move).

In order to achieve the above requirements, the center line of each supporting roller should be skewed by a small angle, so that the supporting roller generates an upward thrust on the kiln body during the rotation process to overcome the downward sliding of the kiln body and make the kiln body slowly Move upwards. When the kiln body reaches the position of the upper stop wheel, a proper amount of lubricating oil can be added to the surface of the supporting wheel to reduce the friction coefficient between the supporting wheel and the tire belt surface, so that the upward thrust of the supporting wheel is reduced, and the kiln body Relying on its sliding force to slowly move downward; when the kiln body reaches the position of the lower stop wheel, the lubrication on the surface of the supporting roller is also gone, and the kiln body begins to move upward again, that is, it moves in another cycle. This is called artificial Swimming method. When using the artificial swimming method, pay attention to controlling the swimming speed of the kiln body. If the swimming speed of the kiln body is too fast, the relative sliding between the contact surface of the wheel belt and the supporting wheel, the large ring gear and the pinion will increase, and slip marks will be produced on the contact surface. Generally, it is advisable to control the rotary kiln to swim once per shift.

The principle of ceramsite calcined in rotary kiln

Because of its many characteristics, ceramsite has its own unique requirements in the selection of raw materials. The process of ceramsite formation can be briefly described as the drying of raw materials to remove moisture, calcination and foaming and ceramic formation, and stable cooling.
