The capacity of these mills is lower than integrated steel mills.
Daswell Rotary Lime Kiln ManufacturerAnd when limestone is strongly heated in rotary kiln, calcium carbonate undergoes thermal decomposition to form calcium oxide, which is quicklime, and carbon dioxide (CO₂). This reaction takes place at 900℃, but the temperature in rotary lime kiln is often around 1000 degrees to make the process happen quickly. But excessive temperature is avoided because it produces unreactive, " dead ...
