New Design Manufacturing Process Limestone Calcination Plant
Description of Active Lime Production Line:
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. We can provide technological solutions and complete production equipment for 50-800TPD quicklime (active lime) production line.
Main Equipments In The Active Lime Production Line:
Grinding Equipment: Ball Mill, Vertical Roller Mill, Batch Ball Mill, Dry Ball Mill, Wet Ball Mill, Horizontal Ball Mill etc
Crushing Equipment: Jaw Crusher, Impact Crusher, Hammer Crusher, Cone Crusher, Rock Crusher etc
Screening Equipment: Vibrating Screen, Circular/Linear Vibrating Screen, Rotary Drum Screen, High Frequency Screen etc

Granulating Equipment: Disc Pelletizer, Pan Granulator, Double Roller Granulator etc
Feeding Equipment: Vibrating Feeder, Apron Feeder, Disk Feeder, Electromagnetic Vibrating Feeder etc
Conveying Equipment: Belt Conveyor, Screw Conveyor, Bucket Elevator, Scraper Conveyor etc
The processing flow of lime production line :
Qualified limestone stores in silos and be shipped through the pre-heater by the elevator into the silos which is on the top of the pre-heater. The pre-heater on the top of silos is consisted of top and bottom level meter controllers which control the feeding capacity.Then through the feed tube the limestone is distributed to the indoor compartment of the pre-heater.
The limestone in the pre-heater is heated to around 900 by the kiln flue gas of 1150 . At this time, about 30% of the limestone has been decomposition. Then the limestone is put into the rotary kiln by the hydraulic stem. In the rotary kiln the limestone sinters and decomposes into CaO and CO2. Then the decomposed
limestone goes into the cooler and is cooled to about 100 by the cold air and then is discharged. The 600 hot air after heat exchange goes into the kiln and combusts with gas. The Exhaust gas blended with the cold wind go to the bag filter through the suction fan and then through the exhaust fan into the chimney.
The limestone out of the cooler enters into the lime storehouse through the vibrating feeder, chain bucket conveyor, bucket elevator and belt conveyor. Whether to carry out screening and other procedures depends on customer requirements.
