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.
