Calcination of Limestone - IspatGuru
Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.

The dilution effect can be accommodated by grinding limestone to higher fineness which improves the early age benefits and would help to increase replacement levels to some extent. Limestone with a mean particle size of 1 μm was found to have lower porosity and higher compressive strength than limestone with a mean particle size of 10 μm .
Calcination of Limestone - IspatGuru
Hence, the process depends on an adequate firing temperature of at least more than 800 deg C in order to ensure decomposition and a good residence time, i.e. ensuring that the lime/limestone is held for a sufficiently long period at temperatures of 1,000 deg C to 1,200 deg C to control its reactivity.
