Product Introduction:
The twin shaft lime kiln adopts the advanced lime calcination principle of parallel flow calcination and countercurrent heat storage. In the calcining chamber, combustion-supporting air, fuel, and materials all flow downward in the same direction from the upper part of the calcining zone, and the materials achieve gradient combustion, thereby avoiding overburning. In the regenerator chamber, the flue gas and materials flow in reverse directions, and the materials and high-temperature flue gas achieve full heat exchange, thereby reducing product energy consumption. At the same time, in the cooling zone, the material and the cooling air circulate in reverse direction to cool the material quickly, thereby increasing the activity of the lime.
Product Advantages:
01
The heat utilization rate is higher, heat loss is less, and the limestone can be heated evenly, thus can improve the calcination efficiency;
02
The burning temperature is high and uniform, thus shortening the burning time, improving production efficiency and reducing energy consumption;
03
During the limestone calcining process, calcium carbonate can be fully decomposed, increasing the activity of calcium oxide;
04
Use advanced control systems and monitoring equipment to monitor temperature, pressure and other parameters during the calcination process in real time to ensure the stability of product quality;
05
High degree of automation, which can improve production efficiency and reduce labor intensity;
06
It has good flexibility and can adjust the production capacity according to actual needs, adapting to different qualities of limestone raw materials and different calcining process requirements.
