The lime rotary kiln, also known as drum rotary kiln, is equipped with an advanced structure and combined flak seal on both ends. It uses complex refractory materials to achieve an air leakage factor of less than 10%, which reduces heat loss. The rotary lime kiln plays a vital role in shortening smelting time, improving product quality, optimizing smelting technology, and enhancing economic benefits.

[email protected]The lime rotary kiln is composed of several parts, including the kiln body, feeding device, fabric device, combustion device, ash discharging device, electric apparatus, instrument control device, and dust removal device. The cylinder is inclined and rotates slowly, causing the limestone to enter the kiln through the kiln end and move down towards the kiln head. Fuel is burned in the kiln through the burner at the kiln head end, and the heat is transferred to the limestone through radiation, convection, and conduction. During this process, the limestone is calcined into quicklime which exits through the kiln head end. Meanwhile, the high-temperature flue gas enters the kiln tail dust removal system through the limestone kiln tail end.
