Active Lime Production Line Lime Calcination Rotary Kiln Lime Kiln
Working Principle of Rotary Kiln
1. With a certain slope to the level, the whole kiln body is
supported by rollers and fitted with thrust rollers to control up
and down movement of the kiln body.
2. Besides main driving unit for driving system, it is also fitted
with the auxiliary driving unit so as to ensure the kiln body still
can rotating when the main motor is powered off and prevent it from
3. The kiln head adopts housing type sealing and kiln rear uses
axial contact sealing unit so that reliability of sealing could be

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 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 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.
