Active Lime Production Line Lime Calcination Rotary Kiln Lime Kiln
Qualified limestone stores in silos and be shipped through the
pre-heater by the elevator into the silos which is on the top of
the pre-heater. The pre-heater on the top of silos is consisted of
top and bottom level meter controllers which control the feeding
capacity. Then through the feed tube the limestone is distributed
to the indoor compartment of the pre-heater.
The limestone in the pre-heater is heated to around 900 ° C by the
kiln flue gas of 1150 ° C. At this time, about 30% of the limestone
has been decomposition. Then the limestone is put into the rotary
kiln by the hydraulic stem. In the rotary kiln the limestone
sinters and decomposes into CaO and CO2. Then the decomposed
limestone goes into the cooler and is cooled to about 100 ° C by
the cold air and then is discharged. The 600 ° C hot air after heat
exchange goes into the kiln and combusts with gas. The Exhaust gas
blended with the cold wind go to the bag filter through the suction
fan and then through the exhaust fan into the chimney.
The limestone out of the cooler enters into the lime storehouse
through the vibrating feeder, chain bucket conveyor, bucket
elevator and belt conveyor. Whether to carry out screening and
other procedures depends on customer requirements.
