Active Lime Production Line Lime Calcination Rotary Kiln Lime Kiln
Process flow introduction: Qualified limestone is deposited in the storage bin, hoisted by the elevator and transported into the top bin of preheater. The top storage bin of the pre-heater is consisted of top and bottom level gages controlling the feeding. And then through the feed tube the limestone is distributed uniformly to all the inside chambers of the pre-heater.
The limestone in preheater is heated to about 900°C by 1150°C kiln gas, about 30% decomposition, pushed into rotary kiln by the hydraulic push rod, and sintered and decomposed into CaO and CO2 in the roatary kiln. After decomposition, the produced limestone goes into the cooler, cooled down to 100°C by the entered cold air and discharged out. The 600 ° C hot air after heat exchange goes into the kiln and combusts with gas. The Exhaust gas goes into the bag filler through draught fan when added into the cold air, and enter the chimney through the exhaust fan.
The lime out of the cooler is transported into lime storehouse by vibration feeding machine, chain conveyor, bucket elevator, belt conveyor according to the customer’s request for whether making the screening other procedures.
