Description
product descriptionRotary lime kiln is the main equipment of lime production line. It is widely used for many industries like metallurgy, chemical industry, building refractory materials, environmental protection, etc. The rotary kiln consists of cylindrical shell, supporting roller, supporting device of thrust roller, driving unit, moveable kiln head, sealing device on the tail of kiln, coal dust pipe device, etc., the kiln body has a certain tilt angle with level. The whole kiln body is supported by the roller supporting device, and it is also equipped with thrust roller device to control the up and down movement of the kiln body.
Limestone Rotary Kiln Process DescriptionMaterial will be feed into kiln tail through chute in gas chamber. As kiln shell is inclined and it rotates slightly, material will move along round shell and will also move along shaft direction from kiln tail to kiln head. Material will be processed through pre-heat, decompose, calcined and will be feed into cooler. Fuel will be given through gas or coal burner at kiln head and will be combusted in kiln. Heat will be transferred to material by fire radiate, hot air flow, kiln brick transfer. The heat will heat and calcine material enough and make it final product.

Rotary Kiln Features1. High Automation LevelThe lime rotary kiln is with advanced structure. Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 20~25% when they enter the kiln. Besides, the lime-stones, with fine fraction about 10~15mm, can be used directly.
2. Waste Heat Reused EffectivelyThe two sides of the reliable rotary lime kiln are sealed by the combined scales, which can make the air leakage coefficient less than 10%. Composite refractory materials should be used in order to reduce the loss of radiant heat.
3. Low Energy ConsumptionThe filling vertical cooler, round or square, can be zoned-ventilation, which can make the temperature of lime-stones in the cooler at about 80°C. As a result, it is very convenient to transport and store. It can also pre-heat the secondary air up to the temperature above 700°C. Then the waste heat can be recycled to reduce energy consumption.
Projects
In 2014, A company in Guangxi Province, China purchased a φ4.0 × 60m lime rotary kiln from CHAENG, the rotary kiln was installed in 2017, and it was put into use in June 2017.
After use, customers made positive comments that machines of CHAENG have outstanding performance and are good at energy-saving to save large cost for users.
