Lime rotary kiln, also known as drum rotary kiln, has advanced structure and reliable scale seal at both ends of rotary kiln. The leakage coefficient is less than 10% using compound refractory to reduce radiant heat loss.

The cylinder body of the lime rotary kiln is rolled up by steel plates, lined with refractory lining and with a specified inclination to the horizontal line. It is supported by three wheels on each supporting device. A large ring of teeth is fixed by a tangential spring plate on the inner cylinder body of the span near the wheel belt at the feeding end, and a pinion meshes with it. When the rotary kiln is in normal operation, the main drive motor transmits power to the open gear device through the main reducer, drives the rotary kiln, and the material enters the kiln from the end of the kiln (the high end of the cylinder). Due to the inclination and slow rotation of the cylinder, the material rolls in the circumferential direction and moves along the axis (from the high end to the low end). The process continues to be completed. Finally, the clinker is generated and cooled by the cooler through the kiln head cover. Fuel is injected into the kiln from the kiln head. After exchanging the exhaust gas and material produced by combustion, the fuel is exported from the kiln tail.

Benefit

The structure of lime rotary kiln is advanced, and the low-pressure loss vertical preheater can effectively improve the preheating effect. After preheating, the decomposition rate of limestone into kiln can reach 20-25%, and the fine-grained limestone of 10-15 mm can be directly used.

Lime rotary kiln reliable combination of both ends of the rotary kiln scale seal. The air leakage coefficient is less than 10% using compound refractory to reduce radiant heat loss.

The circular or square vertical cooler with filling and partitioning ventilation in the lime rotary kiln makes the lime temperature of the outlet cooler 800C+ambient temperature, which is convenient for transportation and storage, and preheates the secondary air into the kiln to over 700 C, thus reducing the number of moving parts and special materials.
