OUR ADVANTAGES
Our rotary lime kiln has many highlights among rotary lime kilns on the market, such as high automation, less energy consumption, wide range of raw materials, high-quality finished products, etc.
Environmental protection, energy saving
Active lime rotary kiln has the characteristics of environmental protection, energy saving, mechanization and high degree of automation (PLC/DCS bus control).
Advanced technology, low energy consumption
The active lime rotary kiln is constantly updating the combustion system. In addition to the conventional coal-fired heat source, clean heat sources such as coal gas and natural gas can also be used. Modern new burner technology is adopted to make full use of energy, especially reducing the impact on the environment during the production process.
Raw materials are adaptable and high quality
The CaO content of the finished product is above 92%, the activity is >320ml, and the advantages of easy maintenance and low energy consumption are regarded as the preferred kiln type by this industry.
Stable operation and high output
The active lime rotary kiln adopts a new type of kiln head and kiln tail sealing technology and device, which has the remarkable characteristics of stable operation and high output.

OUR CASES
rotary lime kiln working process
Limestone is heated to about 900 ℃ by the flue gas of 1150 ℃ kiln in the preheater, and about 30% of it is decomposed. Limestone is calcined and decomposed into CaO and CO2 in the rotary kiln. The lime generated after decomposition enters the cooler, and the cold air blown into the cooler is cooled to below 100 ℃ and discharged. The 600 ℃ hot air after heat exchange enters the kiln to mix fuel with gas. The waste gas is then mixed with cold air to enter the bag filter through the induced draft fan, and then discharged into the chimney through the exhaust fan. Lime discharged from the cooler is sent to the lime silo through the vibrating feeder, chain bucket conveyor, bucket elevator and belt conveyor. The screening and other processes can be added according to user needs.
In the whole lime roasting system, the preheater is divided into several preheating chambers according to different output. Each preheating chamber is equipped with a set of hydraulic pushing device, and is equipped with an automatic control system to transmit relevant data to the PLC control platform of the central control room to achieve central centralized control. This system has a high degree of automation and can realize single point control, making the production process more convenient.
The system balance is emphasized in the process, and the system air leakage and other aspects are improved to make the material and fuel ratio more reasonable, reduce fuel energy loss, and save investment.
Quality indicators: activity of active lime ≥ 360, outlet temperature of waste gas is less than 200 ℃, and dust content of waste gas is less than 50mg/Nm3.
