Rotary Kiln – mechanical issues. – Shell deformation

Rotary kilns are very big and heavy rotating machines. They are characterized by different weights. As it looks in numbers ? For example (only mobile parts) weights: 3-pier kiln, length 50m, weight 610 t. 4-pier kiln, length 80m, weight 1250 t; 7-pier kiln, length 175m, weight 2600 t. As we can see the numbers shows the immensity of this type ...

Rotary Reactor Engineering ScienceDirect

This type of rotary reactor is usually called a rotary kiln and is applied to decompose and sinter a variety of inorganic feed stocks. Thermal energy in the exit gas from the rotary kiln is recovered by application of a preheater. In the preheater, a countercurrent exchange of heat takes place within a vertical moving bed.
