2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). 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.
