Limestone Calcinations Affecting Factors

Jun 04, 2021 Limestone Calcinations Affecting Factors. 1. Limestone Calcinations Temperature. Under normal pressure, the decomposition temperature of limestone is 898 C, and it decomposes rapidly when the temperature is higher than 925 C. When the calcinations temperature is 900 C, the limestone decomposition rate is 3.3mm/h; 1000 C is 6.6mm/h; 1100 C ...


temperature in the kiln is constant, the heat penetration in the particles of limestone is different due to the variation of the size of the limestone. As shown in Figure 5, on larger size stone, heat does not quite penetrate to the core, therefore, the center of these pieces remain as calcium carbonate while the outside is converted to CaO.
