    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.
