Near the support area it can be assumed that the kiln shell deformation is nearly the same as that of the ring. During rotation, deformations will follow a pattern similar to the bending stress distribution curve in Figure 5b. Thus the firebrick wall inside the shell will be damaged, with eventual collapse and interruption of the kiln operation.
