200-1200t/d QuickLime Poduction Line RPC project
Hengyang Industry can undertake the 200-1500t/d quick lime
production line EPC, including the the reach report, civil
engineering, designing, equipment, installation and debugging ---
"turnkey” service with production capacity and standard achieved.
Capacity: 200-1200t/d Kiln slope: 3.5~4% Diameter: φ1.8~φ4.8 m
Application: Lime production plant, cement plant, Hydrogen calcium
plant
Quick Lime Production Line Process:
1.Preheating
Limestone is heated to 900℃ by the 1150℃ kiln gas in the preheater
of 1000t/d active lime production line.
2.Calcining
Hydraulic push rod of this active lime equipment sends the
limestone into the rotary kiln. The limestone is calcined and
decomposed into CaO and CO2.
3.Cooling
Decomposed limestone is then sent into cooler of the active lime
production line. The lime is cooled to less than 100℃ by cold air
and then is discharged out.
4.Waste Gas Treatment
The 600℃ hot air enters into kiln and burns with coal gas. The
waste gas is then mixed with cold air. Draft fan of this active
lime equipment sends the waste gas into bag dust collector. Exhaust
fan then discharges the waste gas into chimney.
5.Storing
After coming out of the cooler, the lime is transported to
limestone storage silo of the 1000t/d active lime production line
by vibrating feeder, chain bucket elevator and belt conveyor.
