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.
