Product Description

High Efficiency  Active Lime Rotary Kiln Used for Mining, Quarry



Application of rotary kiln:
1) Rotary kiln is the key equipment in cement industry for calcining clinker.
2) It is also used in various industries, such as metallurgy, chemistry, building, refractory material, environmental protection, etc.

3) The kiln is composed of the cylindrical shell, roller supporting device with thrust roller, driving gear unit movable kiln hood, sealing device at kiln inlet, coal dust pipe device etc.



During all the active lime production process, the rotary kiln production process is the most advaced 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. We can provide technological solutions and complete production equipment for 50-800TPD quicklime (active lime) production line



Production Process  of quciklime plant 
10-50mm Qualified limestone are fed to receiving hopper by loader. The vibrating feeder under the hopper will feed limestone to inclined belt and then transport to screening equipment. After screening, the limestone will be transported to the top silo of preheater by inclined belt conveyor.Limestone are fed from top silo to preheater through feeding chute. At the meantime, the hot air from rotary kiln will preheating the limestone to more than 1000ºC and also can partially decomposed. Preheated limestone are pushed into kiln inlet by hydraulic pusher and discharged into vertical cooler after calcination at rotary kiln. The cooling air blows by fan can cool down the temperature of material to room temperature +60ºC and then discharged ot of vertical cooler.After discharging from vertical cooler, active lime will be transported to lime silo by apron conveyor, bucket elevator and belt conveyor.Temperature of hot air from rotary kiln can be reduced to 250ºC after heat exchange with limestone inside the preheater. Then the hot air will flow into cylcone dust collector for primary dust collecting. After bigger size dust are collected, the waste air will flow into bag filter for secondary dust collecting. The emission dust concentration is less than 50mg/m3
