Advanced Design Active Lime Line from china, Lime rotary kiln For Sale
Lime Production Line Introduction:
Lime production line refers to the whole process of active lime
production. During all the active lime production process, the
rotary kiln production process is the most advanced one. Our
production process adopt the rotary kiln with the vertical
preheater and vertical cooler for the limestone calcination to
achieve the production requirements of energy saving, environmental
protection, the high activity.
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.
