Many rotary centerline adjustment method. However, different methods of measurement the measured result is not the same. For example: theodolite measurements, lighting method and hanging wire method. These different methods, once identified the kiln and vertical centerline offset value can be based on this value, the adjustment by the tug to complete centerline alignment. Rotary kiln is divided into horizontal centerline adjustment adjustment and vertical deviation deviation adjustment, adjust the horizontal deviation case, if a gear wheel with the centerline needs to move horizontally at 1mm, the equivalent of one pair tugboat level should also move in the same direction 1mm, in the case of the vertical deviation adjustment, if a gear wheel with a kiln to raise or to lower the centerline 1mm, then a corresponding pair of outer tug should also move horizontally inward or 2mm. Only skilled measurement techniques, for the operation of the rotary kiln will be most beneficial, horizontal centerline of the rotary kiln and vertical deviation deviation is preferable to use an adjustment. Specific operations before the adjustment, the first stopper at the kiln based on each level of deviation of the center line and the vertical movement of the moving amount of deviation, calculated for each tug and horizontal movement of the algebraic values ​​of the level and then adjust the moving position of each tug. As a result of repeated tug to avoid movement. The above article by Henan YuFeng Heavy Machinery finishing release, reproduced, please indicate the source!
