Rotary Kiln Alignment. The continuity of operation of a lime sludge kiln requires strict maintenance control. The rotary kiln is among the largest type of moving machines made and is subjected to extreme temperatures, power failures, atmospheric conditions, varying loads, and other operating conditions which affect its wear and alignment.
All rotary kilns gradually become misaligned over time as a result of normal operation, meaning kilns should be routinely realigned as part of a preventative maintenance program. It's important to recognize that any significant maintenance or repairs can also affect kiln alignment, so kilns should always be realigned after any major repair work.

The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval ...
