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.
