✅Rotary Lime Kiln – Advanced Active Lime Production Solution
The rotary lime kiln is a highly efficient industrial furnace designed for producing high-quality active lime through precise limestone calcination. Featuring an optimized structure and stable operation, our energy-saving kiln system integrates a low-pressure vertical preheater, achieving up to 30% pre-decomposition efficiency before materials enter the rotary chamber.
Key Benefits:
✔ Multi-Fuel Flexibility – Compatible with pulverized coal, liquid fuels, and various gases
✔ High-Activity Lime Output – Ensures superior quality for demanding applications
✔ Industry-Proven Performance – Widely adopted in steel, chemical, construction, and environmental sectors
Engineered for energy efficiency and operational reliability, our rotary kilns deliver consistent results while minimizing environmental impact.
✅Customized Rotary Lime Kiln Solutions for Every Need
Our company offers 11 standardized models from Ø2.5×40m to Ø5.1×72m, with matching YRQ vertical preheaters (YRQ04-YRQ20) and LSF vertical coolers (LSF36-LSF112) – delivering 150-1200 t/d production capacity to suit operations of all sizes.

✅Industrial Applications
Our advanced lime kiln systems are engineered for precision calcination across key industries:
1.Metallurgy: High-purity lime for steelmaking and non-ferrous metal processing
2.Chemical Industry: Essential for calcium compounds and environmental treatments
3.Building Materials: Production of high-quality lime for cement and construction applications
✅Type of Lime Kiln
Beyond our flagship lime rotary kilns, we offer:Lime vertical (shaft) kilns: Compact footprint with energy-efficient performance
✅Our Advantages
1. The output of the rotary kiln is stable and suitable for large, medium and small active lime production lines.
2. The rotary kiln is an open calcination, with a simple kiln structure, uniform heating, stable product quality, and low raw burning and overburning rates;
3. The vertical preheater at the end of the kiln can make full use of the high-temperature flue gas generated by calcination in the rotary kiln to increase the output of the rotary kiln;
4. The vertical cooler at the head of the kiln can not only quench the high-temperature lime and improve the activity of the product, but also facilitate transportation and storage
