The "calcimatic" kiln, or rotary hearth kiln, is a circular kiln with a slowly revolving doughnut-shaped hearth. In fluidized bed kilns, finely divided limestone is brought into contact with hot combustion air in a turbulent zone, usually above a perforated 11.17-2 EMISSION FACTORS 2/98 Figure 11.17-1.
Calcination - Wikipedia
The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide, in order to create cement. The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment. Calcination is carried out in furnaces or reactors (sometimes referred to as kilnsor calciners) of various designs including shaft furna…

Calcination step 4: In the rotary kiln — Science Learning Hub
Nov 15, 2012 · The rotary kiln is 60 m long and 3 m in diameter. It rotates at 1 rpm. Coal is ground to a fine powder, mixed with air and blown into the rotary kiln, where it ignites, producing the necessary heat. Theoretically, to convert 1 tonne of limestone into lime, 3.17 GJ of heat energy is required, as the stone reaction occurring is endothermic.
