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 …
Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end (the fire wall). As the kiln rotates, the heated material climbs the kiln wall before flopping down and flipping over. With each flop, the material travels a short distance along the length of the kiln because it is at a slight angle.

4. Make sure the kiln load is even. You can create multiple levels separated by Kiln Shelves (Batts made from cordierite or other kiln-safe material) and Props (support pillars) of varying heights. Choose pieces to load based on height. Load tall pieces on one level, and shorter pieces on another.
Rotary kilns are traditionally large steel pipes, several meters in diameter and up to 100 m in length (in larger facilities, however, kiln lengths of over 100 m are not uncommon). To protect the steel from intense heat, however, each kiln is lined with bricks composed of refractory material, which is typically a blend of various ceramic compounds.
