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.

Rotary Kiln refers to rotating calcination kiln, belongs to
construction material equipment. According to different materials,
rotary kiln can be divided into cement kiln, metallurgy chemical
kiln and lime kiln. The cement kiln is used for makeing cement
clinker and there are dry and wet methods to make cement.
Metallurgy chemical kiln is applied in metallurgy industries and
ironworks for lean iron ore, chromium ore and ferronickel ore
calcination. Lime kiln is mainly used for calcine dolomite and
active lime which is used in steel plant and ferroalloy factory.
