Preheater-kiln lime calcining systems -

long rotary lime calcining systems, but it is the KVS preheater/rotary kiln system approach to lime calcining that is the technology of choice for the more demanding applications. The preheater-kiln system can be designed to process limestone feed as large as 75mm or as small as 6mm, with a nominal 4:1 ratio of largest to smallest.
