Lime Production from Limestone - Current Technology

3) Lime Calcining (Conversion of limestone (CaCo3) to lime (CaO)) Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.

Lime calcining systems -

Lime calcining is the conversion of limestone (CaCO3) to lime (CaO). Limestone is a sedimentary rock, the third most abundant mineral. Limestone is mostly quarried above ground; however, some underground limestone mining is done. Limestone is found with many different characteristics and different impurities. The limestone characteristics change from different parts of the world and even .

Lime kiln - Wikipedia

A lime kiln is a kiln used for the calcination of limestone to produce the form of lime called quicklime. The chemical equation for this reaction is CaCO3 + heat → CaO + CO2 This reaction takes place at 900 °C, but a temperature around 1000 °C is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime can be .
