High Quality Active Lime Production Line, Reliable Chinese Supplier
Price
OUR ADVANTAGES
We can provide technological solutions and complete production
equipment for 50-1000TPD quicklime (active lime) production line.
We adopt the new type, energy saving and environmental system,
through which fuel consumption can be reduced 40%, output capacity
increased 30%.
1. Advanced Technology: The calcination process adopts pre-heater+
rotary kiln+ vertical cooler system, it can reduce the fuel
consumption 40%, and increase output capacity 30% due to reuse the
waste gas in the system.
2. High Automation Level: The Production line is arranged with
temperature and pressure monitoring instrumentation, operating
parameters of the computer display, the production line can adopt
the advanced computer control, to achieve automatic operation of
the entire system.
3. Mature Experience: We have professional engineer team, mature
experience, and over 100 successful project cases from home and
abroad, to maximize your investment costs and meet the customized
solution demand.
4. Good dust collecting treatment: The cyclone dust collector and
pulse bag filter can control the dust emission is lower than China
standard.
Process Flow of Lime Production Line
Step One: Raw Material Preparation
1. Limestone: The particle size of limestone should be between
10～40mm. The proportion of limestone size above 40mm or below 10mm
should not be more than 5%. The maximum size should be less than
40mm.
2. Fuel:Furnace gas, gas, coalbed methane, pulverized coal could be
used as fuel.
Step Two: Raw Material Feeding
Limestone in the plant yard will be carried by tractor shovel and
fed to hopper, it will be discharged from hopper to vibrating
feeder and sent to vibrating screen for screening through belt
conveyor. The size ≥20mm will be sent to pre-heater by conveyor.
And size less < 20mm will be carried away.
Step Three: Limestone Calcination
Limestone in the pre-heater will be preheated by the hot air, then
it will be discharged to rotary kiln through chute that connecting
pre-heater and kiln, it will stay in the kiln for 1.5-2 hours for
calcination, during the process, it will be calcinated with
temperature around 1300 ℃, after which comes limestone
decomposition and release of co2,then the for mation of quick lime
qill be completed.
Step Four: Finished Products Conveying
Lime will be discharged to a chain conveyor by vibrating feeders in
the bottom of vertical cooler, it will be lifted to lime in the
storage hopper can be used for dispatch or transported to the
hydration workshop.
Step Five: Dust Filtering System
There are two dust filtering systems, one is in the kiln inlet,
dust will be filtered by bag filter then the clean gas will be
released to air. The other is dust from lime storage hopper and the
feeding part of bucket elevator, dust will be filtered by bags and
then released to air.
