Cement Kilns: Precalciner kilns

Precalciner cement kilns. As with conventional suspension preheater kilns, the gases leaving the top of the preheater are used for drying raw materials. Some heat is still wasted, because rawmills tend to run intermittently, since they are always designed with "overtaking capacity" to avoid restricting the output of the kiln.

Cement Manufacturing

Rotary kiln, in which the cement is burnt at 13001500 °C, is a long cylinder rotating on its axis and inclined so that the material fed in at the upper end travel slowly to the lower end. For dry process the rotating speed of the kiln is normally in the range of rpm.
