Chaeng (Great Wall Machinery) can undertake the 200-1500 t/d activity lime production line EPC, including the reach report, civil engineering, designing equipment, installation and debugging---"turnkey" service with production capacity and standard achieved.

Lime Production Line Processing

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 lime 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.
