In order to extend the rotary kiln service time, Great Wall mechanical engineers believe that from the controlling rotary kiln axis offset and reasonably determine the rotary kiln tyre to reduce the thermal stress can achieve this goal. This article mainly analyzes the method of efficient use of lime rotary kiln from the point of view of controlling the rotation of the rotary kiln axis.

Rotary kiln axis offset control. During the actual production process, strictly control the kiln axis offset shall not exceed 3mm.

Practice has proved that when the rotary kiln body in the hot state under the axis adjustment is accurate, the cylinder bending and twisting are reduced to the smallest, the distribution of the load on the fulcrum is also more appropriate, kiln refractory bricks, large kiln cylinder, The pressure of the refractory bricks is obviously decreased, the service life is obviously prolonged, and the operation rate of the kiln can be greatly improved. Therefore, it is necessary to strengthen the hot-state rotation of the kiln axis on-line detection and deviation of the timely correction work. There are two ways to adjust the kiln axis: one is in the kiln condition, in the kiln inside the various fulcrum and large gear axis, the use of light beam, while adjusting the roller side of the rotary kiln axis adjustment in a straight line On the other; in the rotary kiln in the hot state of operation, from the outside of the kiln to find the pivot of the various fulcrum, and then adjust the roller side of the rotary kiln axis adjustment in a straight line.

Practice has proved that the later is more effective.
