Calcination of Limestone – IspatGuru

2013-5-2  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

Calcination - Burning Limestone Unity Lime

Calcination – Burning Limestone. Quarried stone is crushed and transported to a lime kiln. The lime burning process within the kilns requires enough heat to be transferred to the limestone in order to decompose the calcium and magnesium carbonates. Heat transfer for lime burning can be divided into three main stages:
