The rotary kiln is operated under the condition of high temperature replanting for a long time, which will cause the tug, the belt to wear and the bending deformation of the cylinder, so that the rotation can not maintain a straight line, causing unnecessary damage and delaying the loss of the calcination operation, so the central axis is performed. Regular measurements and repairs if necessary. The central axis measurement itself is a very complicated task, and the measurement methods that can generally be used are not difficult.

 

    One method of measurement is to determine the center point of the kiln by measuring the distance between the reference vertical plane and the kiln body by the horizontal plane. This measurement method is not very convenient in operation, and the problem mainly occurs in measuring the distance between the horizontal reference and the cylinder. It is necessary to measure the kiln body that is close to the high temperature operation, and to perform high-altitude operation. There are artificial observation errors and certain dangers that are difficult to estimate, so it is relatively difficult to operate.

 

    Another method is to set the position of the three different points on the kiln before the measurement to determine the center position of the kiln. This method does not need to measure the diameter of the roller and the kiln, which reduces the existence of the measurement process. Indirect error, using contact sensors for testing, although it will be affected by vibration and high temperature, but the ground monitoring system can avoid the measurement error caused by the vibration of the kiln pier.
