Owing to the poor thermal efficiency of earlier long kilns and the need for fuel efficiency, most designs are aimed at maximizing mixing and heat transfer. To accomplish this, kilns are often equipped with heat recuperators, such as preheaters, in which part of the energy in the exhaust gas is recovered to preheat the feed before it enters the .

Cement Kilns: Precalciner kilns

This optimisation of thermal efficiency allows a large output to be produced by a relatively small kiln. The kiln solely performs the sintering process, for which the rolling action of the rotary kiln is indispensible. A number of distinct advantages of air-separate precalciners has resulted in their almost universal use in modern cement plants.

LUX SIGNIFER: The Rotary Kiln Evolution

Because this new type of kiln had much greater capacity and burned more thoroughly and uniformly, it rapidly displaced the older type kilns. It has been further mentioned that the factor that contributed to the tremendous surge of Portland cement between 1880 and 1890, reportedly from about 42,000 to 335,000 barrels, was the development of the rotary kiln (Blezard, 1998).
