ABSTRACT:
An apparatus for and method of adjusting the effective length of a rotary kiln. Preheating gas enters the kiln, passes over a portion of the material to be heated and exits the kiln through an axially extending exhaust duct. Changing the length of the duct modifies the amount of time the material is subjected to direct heating by the gas so that the effective heating length of the kiln is changed.
