Lime Calcination Process

Rotary Klin for Lime Calcination

Lime Calcination is a process where limestone (CaCO₃) undergoes thermal decomposition in a rotary kiln, converting it from limestone (CaCO₃) to quicklime (CaO) with temperatures heated to over 900°C. By this method, carbon dioxide is separated from limestone, producing reactive and highly pure lime that’s used in many commercial settings. Modern rotary kiln systems are carefully designed so that the heated lime is uniform in quality.

Rotary kilns from Technomart India are manufactured to give efficient lime calcination results. We have systems that maintain stable high temperatures, allow you to select desired processing conditions, and automate controls for constantly high-quality calcination outcomes. Since our kilns are strong and power-saving, they can process many kinds of limestone with low operational costs and high daily volumes.

Features of Lime Calcination

• Controlled CO₂ Release – The specific combustion system and stable temperature in a rotary kiln guarantee that calcium carbonate breaks down slowly, resulting in uniform product quality without shocks.
• Enhanced Lime Reactivity – When the kiln is heated properly and holds the product for the proper time, it allows the quicklime to crystallize finely and react more easily chemically, which counts for applications like making steel and treating water.
• Advanced Material Flow Design – With the use of adjustable slanting and lifting, the kiln ensures constant rotation, even heat throughout, and lessens the risk of uneven material burn.
• Versatile Feed Compatibility – No matter if the limestone has mixed-sized or coarse particles, the technology can handle it without affecting the materials and provides optimal solutions.
• Dual-Zone Thermal Control – The kiln is designed for each of the section's preheating, calcination, and careful cooling and can be independently set up. As a result of segmentation, the lime produced is purer and there is less energy wasted during the thermal treatment.
