Product Description

Product description

This active lime production line is a complete line that includes vertical preheater, rotary kiln, grate cooler, air treatment system, raw material conveyor system, finished product conveyor system, raw coal grinding system, and so on. DCS central control system is employed to make concentrated operation management. CHAENG can undertake the 200-1500t/d active lime production line EPC, including the the reach report, civil engineering, designing, equipment, installation and debugging --- " turnkey" service with production capacity and standard achieved.
 
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 900ºC heated by kiln flue gas of 1150ºC, 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 100ºC 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.

 Projects

In 2014 , a building material factory from guangxi province of China purchased a lime production line with annual output of 400,000 tons. The main equipment includes φ4.0×60m rotary kiln, φ2.4×4.75m coal mill, 5000 m² bag type dust collector. And all of these equipment were made by CHAENG independently, and CHAENG provided installation and commissioning guidance.
