Medium Scale Coal Fired Complete Plant For Producing Quick Lime
Prodiction Process
Step One Raw Material Preparation
1. Limestone: The particle size of limestone should be between
10~40mm. The porportion 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 couldbe
used as fuel.
Step Two. Raw material feeding
Limestone in the plant yard will be carries by tractor shovel and
feed to hooper, it will be discharged from hooper to vibrting
feeder and sent to vibrating screen for screening through belt
conveyor. The size ≥20mm will be sent to preheater by conveyor. And
size less than 20mm will be carried away.
Step Three. Limestone Calcination
Limestone in the preheater will be preheated by the hot air, then
it will be discharged to rotary kiln through chute that connecting
preheater and kiln, it will stay in the kiln for 1.5- 2 hours for
calcination. During the process, it will be calcined to 1300 ℃
temperature. After that, it comes limestone decomposition and
release of co2, then quick lime production will be completed.

Step Four. Finished Products Conveying
Lime will be discharged to a chain conveyor by vibrating feeders in
the bottomof vertical cooler, it will be lifted to lime in the
storage hopper can be usedfor 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 befiltered by bag filter then the clean gas will be
released to air. The other isdust from lime storage hopper and the
feeding part of bucket elevator, dustwill be filtered by bags and
then released to air.
