Lime Rotary Kiln

Effectively improve the preheating effect, the decomposition rate of the preheated limestone into the kiln can reach 20-25%, and the reliable combined scale seal at both ends of the rotary kiln can be directly used to use 10-15mm fine-grain limestone, so that the air leakage coefficient is less than 10%. The kiln lining uses composite refractory materials to reduce radiant heat loss. The rotary kiln has simple structure and reliable operation. The production process is easy to control automatically

Information

The limestone in the preheater is heated to about 900°C by the kiln flue gas of 1150°C, and about 30% of the decomposition is pushed into the rotary kiln by a hydraulic push rod. The limestone is decomposed into CaO and CO2 by sintering in the rotary kiln. The decomposed limestone enters the cooler, where it is cooled to 100°C by the blast of cold air. After the heat exchange of 600°C hot air into the kiln and gas mixed combustion. The exhaust gas is mixed into the cold air through the induced draft fan into the bag dust collector, and then through the exhaust fan into the chimney.
