Product Details:

We can provide technological solutions design and complete equipments fabrication for 50 TPD - 1200 TPD quicklime (active lime / hydrated 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%.

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. FeedingLimestone 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 CalcinationLimestone 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 complete.

Step Four: Finished Products ConveyingLime 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 SystemThere 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.
