Why migration is necessary in kiln

Due to the difference in kiln shell outer and tyre inner diameter,kiln revalotion is more then tyre.The slippage of shell inside tyre is called migration.When tyre and kiln become rigid so the air gap become zero between both and migration get zero.Migration tell us only that there is air gap.actual air gap is necessery for shell expantion.

OPERATIONS STRATEGIES FOR VERTICAL SHAFT LIME KILNS

primary advantage of vertical kilns over rotary kilns is the higher fuel efficiency. The primary disadvantages of vertical kilns are their relatively low production rates and the fact that coal cannot be used without degrading the quality of the lime produced. Other much less common kiln types include rotary hearth and fluidized bed kilns.

Continuous, External Heating Type Rotary Kiln

Summary. This machine is an indirect heating type of rotary kiln using electricity, heavy oil, or gas as the heat source. The shell, due to its equilateral hexagonal cross section, minimizes the shear of the material layer to provide a sharp distribution of residence time, enabling you to get stable and high quality products of uneven firing.
