Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven off, leaving calcium ...

A PFR (Parallel Flow Regenerative) kiln has two vertical shafts with a connecting crossover-channel. Both shafts work together: one calcines the product, the other preheats the kiln feed. This process works in cycles, switching the functionality of the shafts from "burning shaft" to "regenerative shaft" every 10-15 minutes.
