Introduction
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkalinecrystalline solid at room temperature. The broadly used term “lime” connotes calcium-containing inorganic materials, which include carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate, such as limestone. By contrast, “quicklime” specifically applies to a single chemical compound.
Manufacturing Process of Calcium Oxide
Lime Stone is extracting from quarries & Sized through a Crusher. Then Sized Lime Stone is transported to Lime Kilns. To Calcine Lime Stone there must be a significant transfer of heat to the Lime Stone. There is 3 stages of Calcination process [1] Preheating [2] Calcination [3] Cooling.
