Adjustment of new wet mill

The new wet mill just put into production, after running for a period of time, because the concrete foundation of each block wheel group sinks to different degrees, the tug wheel is not adjusted correctly during installation, and the degree of wear on the supporting parts in the rotary kiln is not the same. In the process of maintenance and replacement of the supporting parts, the influence of the size of the new and old parts was not considered. The insufficient hardness of the rotary kiln itself and the inadequate operation will cause the center line of the rotary kiln to bend and be destroyed. This will waste a lot of power in the rotary kiln, the sealing device will lose its original function, and the kiln body will be cracked, which is directly related to the operation of the wet mill. Therefore, we need to measure the center line of the rotary kiln and correct it. The linear recovery must be carried out regularly, only in this way can the normal operation of the rotary kiln be guaranteed.

There are many methods for aligning and measuring the center line of the wet mill, such as theodolite measurement method, light emitting method, and wire hanging method. Through these different measurement methods, once the deviation value of the kiln center line and the vertical direction is found, the center line can be adjusted through the adjustment of the tug according to this value.

The adjustment of the center line of the kiln is divided into horizontal deviation adjustment and vertical deviation adjustment:

(1) In the case of horizontal deviation adjustment, if the center line of a certain wheel belt needs to move 1 mm horizontally, it is equivalent to a pair of tugs should move towards Move 1 mm horizontally in the same direction.

(2)In the case of vertical deviation adjustment, if the center line of a certain wheel belt kiln needs to be raised or lowered by 1 mm, the corresponding pair of tugs should move 2 mm inward or outward at the same time.

After detailed analysis, it is best to adjust the horizontal deviation and vertical deviation of the center line of the rotary kiln at one time, which is the most beneficial for the operation of the rotary kiln. The specific operation is: before adjusting the wet mill, calculate the algebraic sum of the horizontal movement of each tug according to the movement of the horizontal deviation and the movement of the vertical deviation of the kiln center line at each block, and then adjust the level of each tug. ’S mobile location. In this way, repeated movements of the tug can be avoided. The one-time adjustment of the wet mill is not only fast, but also very accurate. It is a very efficient adjustment method.
