 Active lime kiln system process Description: Qualified limestone stored in the silo, the elevator upgrade and transported into the preheater at the top of silo. Preheater top of the silo, the upper and lower 2 level gauge control with quantity, and then cutting through the pipe will be evenly distributed to the preheater limestone Calvary room. 
 Limestone in the preheater kiln is 1150 ° C flue gas heated to about 900 ° C, about 30% of the decomposition, by putting into the hydraulic rotary kiln, the limestone in rotary kiln decomposed by sintering of CaO and CO2. Generated after the decomposition of limestone into the cooler, the cooler into the cold air inside the drum was cooled to about 100 ° C discharge. The heat exchange of 600 ° C hot air into the kiln and gas combustion. The exhaust fan in the cold blended into the bag filter, and then enter the chimney through the exhaust fan. 
 A cooler by the vibrating feeder lime, chain bucket conveyor, bucket elevator, belt conveyor into the lime finished products. Green lime kiln according to customer requirements whether screening processes.
