Traditional Rotary Lime Kiln Process. The long rotary lime kiln has the characteristics of simple structure and stable operation. It increases the length of the rotary kiln cylinder to improve the preheating effect and after preheating the limestone is entering into the calcination zone for decomposition; The limestone feeding size can be 10 ~20 mm 20~40 mm.
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate).The chemical equation for this reaction is:. CaCO 3 + heat → CaO + CO 2. Limestone is poured into one side of the kiln, it is then heated up with hot air and quicklime [Calcium Oxide] comes out the other end.
