An Overview of Lime Slaking and Factors That Affect the …
The following is a brief chemical formula of this process: (Limestone) CaCO3 + HEAT (Calcium Oxide) CaO + CO2. However, CaO is unstable in the presence of moisture and CO2. A more stable form of lime is calcium hydroxide Ca(OH)2. Therefore, 56 units of CaO plus 18 units of H2O results in 74 units of Ca(OH)2.
How Lime is Made
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
