Rotary Kiln – IspatGuru

 · The size of a rotary kiln is not only a function of capacity, but also of the amount of heat which can be generated inside the rotary kiln from the volatizing and/or combustion of the material. The diameter and length of the rotary kiln are calculated based on the maximum feed rate, the required retention time, and what the bed profile (how full of material is in the rotary kiln) is required ...

Cement Kilns: Wet and semi-wet process kilns

The resulting "cake" could be fed directly to a rotary kiln - typically a converted wet kiln, or dried out in a preheater before feeding to a dry process kiln. The first example of the former was at Billingham in 1929, where ICI, who had plenty of experience of vacuum filtration in their other processes, used this for forty years to reduce slurry moisture to a consistency rather more like ...
