Abstract
A method of manufacturing cement clinker includes a rotary cement kiln having a feed end, a mid-kiln feed location, and a burning end. The rotary kiln is tilted downwardly from the feed end to the burning end so that material introduced into the feed end travels downwardly to the burning end. Heat is directed at the burning end of the rotary kiln. Raw feed material is introduced in the feed end of the rotary kiln. Calcined material having a particle diameter of up to 12 inches is introduced at the mid-kiln feed location. The mid-kiln feed location is arranged in a calcining zone of the rotary kiln.
