The limestone is heated to about 900°C by 1150°C kiln flue gas in the preheater, and about 30% decomposes. It is pushed into the lime rotary kiln by the hydraulic push rod, and the limestone is sintered and decomposed into CaO and CO2 in the rotary kiln. The limestone generated after decomposition enters the cooler, and is cooled to below 100 ...
