The lime rotary kiln, also named drum rotary kiln, is equipped with advanced structure and combined flak seal on both ends. It incorporates complex refractory materials to achieve an air leakage factor of less than 10%, thereby reducing heat loss. Rotary lime kiln plays an extremely important role in shortening smelting time, improving product quality, optimizing smelting technology and improving economic benefits.

[email protected]Lime rotary kiln mainly consists of kiln body, feeding device, fabric device, combustion device, ash discharging device, electric apparatus, instrument control device, dust removal device, etc. Due to the inclination and slow rotation of the cylinder, limestone enters the kiln through the kiln end and moves from the lime kiln end (high end) to the kiln head (low end). The fuel is burned in the kiln through the burner from the kiln head end and the heat is transferred to the limestone by radiation, convection and conduction. The limestone is calcined into quicklime during the movement and comes out of the kiln head end, while the high temperature flue gas enters the kiln tail dust removal system from the limestone kiln tail end.
