Process Description

Qualified limestone (20 ~ 50 mm) are lifted by bucket elevator to top silo of preheater. There are two level indicators (up and down) controlling the feeding amount, then they are separated averagely into preheaters’ individual rooms. The limestone’s temperature rises to about 900℃ heated by kiln flue gas of 1150℃, about 30% of them are decomposed, and they come into the rotary kiln by hydraulic rod, where the limestone decomposed into CaO and CO2. The decomposed limestone are put into the cooler, where its temperatures drops to 100℃ and released. The hot air (600°C) will come to kiln after heat exchange, and mix with coal gas for mixture combustion. The exhaust gas is released by the blower into bag deduster through multi-pipe cooler, then into the chimney though exhaust blower. The limestone from the cooler will be transported to the limestone final product silo through vibrating feeder, chain conveyer, bucket elevator, belt conveyer.
