Vibration failure of lime rotary kiln

Published 2015/1/21 10:44:54

The main manifestation of vibration of lime kiln is big vibration in horizontal direction and vertical direction. As axial vibration is not big, locating place of riding wheel has changed. Therefore vibration is caused by deflection of lime rotary kiln center line.

For transient vibration, the following scheme shall be adopted according to measuring result of lime rotary kiln center line and in combination with equipment operation.
Adjust riding wheel by taking measuring result as guidance direction.
As the adjustment process is correction process of kiln shell, force condition of riding wheel and tyre will change after adjustment. So the principle of “making adjustment while checking” shall be adopted for adjustment. The next adjustment can be conducted after adjustment is completed and observed it about one day.
In adjustment process, barrel temperature, riding wheel bush temperature, kiln speed, inventory rating, hydraulic thrust wheel pressure and other data shall be recorded, and bearing bush oil film formation condition and vibration of kiln shall be observed to compare change before and after adjustment. In combination with vibration change of lime kiln in adjustment process, measures on restructuring shall be taken correspondingly if it gets better after several adjustments, and otherwise, it shall be set back.
