Product Description Supply Active Lime Production Line with Long Warranty Product Description 1.Introduction of calcined lime plantWe can provide technology solutions and complete calcined lime plant for quicklime (active lime) production.-Design capacity:50-700TPD-We have professional engineer team. -We have mature experience, and project cases more than 100 till 2011. -Using the new type energy saving and environmental system, reducing fuel consumption 40%, increase output capacity 30%. 2. Production process description of calcined lime plantRaw material feedingThe limestone in the plant yard will be carried by tractor shovel and feed 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.Calcination The limestone in the pre-heater will be preheated by the hot air, then it will be discharged to rotary kiln though 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 a temperature around 1300 °C, limestone decomposition, release of CO2, become calcined lime. Then the lime moves to vertical cooler for cooling.Calcined lime conveying Calcined lime will be discharged to a chain conveyor by vibrating feeders in the bottom of vertical cooler, it will be lifted to storage hopper by bucket elevator. So the lime in the storage hopper for dispatch or hydration workshop. Dust filteringThere are two dust filtering systems, one is in the kiln inlet, dust will be filtered by bag filter then the clean gas will release to air. The other is dust from lime storage hopper and feeding of bucket elevator will be filtered by bag filter then release to air.
