Rotary Kiln mechanical issues. Shell deformation

Tolerance given by most kiln producers is from 3-6mm. So this situation is a warning to kiln operators. Temperature parameters has a very important impact of tireshell operation. For initial clearance there is always a temperature limit for expansion. Different thermal expansion of shell and tire can lead to some shrinkage tire on shell.
