Production Line of AAC Production line/AAC block

AAC Aerated concrete is the lightweight artificial stone, adopting the calcareous material and the siliceous material as components, forming the porous structures by the way of chemical gas generation, and obtaining the intensity after autoclaved curing. The calcareous material is mainly lime and cement, the siliceous material generally is industrial waste in China, such as fly-ash, tailings etc, or quartz sand.   China hot sale AAC making plant,autoclaved lightweight block machine,lightweight block plant,clc plant   

Main Process Flow of AAC Production line/AAC block

1. Raw material: Store the fly-ash (tailings etc), lime and gypsum after milling to the needed fineness (200 mesh)  China hot sale AAC making plant,autoclaved lightweight block machine,lightweight block plant,clc plant
2. Mixing the fly-ash, cement, lime, gypsum and water in the pot after batching.
3. Promote the slurry temperature to 40-50 degree by steam, and mill with aluminum powder for 1min.
4. Pour the slurry into the mould, and still in the curing room for frothing in 2-2.5h.
5. Cut it in to needed size by the cutter after the slurry approach the cutting intensity, and place the block on the trolley.
6. Autoclaved curing after the trolley enter into the autoclave (vacuum, rise the pressure, keep the pressure, reduce the pressure),keeping the constant pressure 1.2MPa. The whole process needs about 12h.
7. The products out of the autoclave are placed in a stack. We can recycle the scrap and the waste water from the whole production.     

Storage and Process of Raw materials of AAC Production line/AAC block

(1) fly ash(sand)and gypsum
 During process, proportioned fly ash(sand)and gypsum are put into Slurrying tank and made into mixing slurry. Then it is pumped into the slurry storage tank by slurry pump as standby.

(2)Quick lime 
The bulk quick lime is conveyed to the lime storage by bucket elevator after being crushed by swing jaw crusher(Or: The bulk quick lime is conveyed to ball mill by belt conveyed after being crushed by swing jaw crusher),then the lime powder after being grinded fine by ball mill is conveyed to the lime powder storage in ingredient building as standby.

(3)Cement 
The cement adopts bulk cement(ordinary portland cement (325#) or portland cement (425t)),and it is pumped into the cement powder storage in ingredient building as standby

(4) Aluminum powder 
Aluminum power is poured into aluminum mixing machine to mix into 5% slurry as standby after being metered by workers.

Dosing & mixing & pouring of AAC Production line/AAC block

The metered slurry pours into the pouring & mixing machine according to order, and at same time, the dumping device of electronic scale discharges the metered lime and cement powder to pouring and mixing machine. Then the slurry in Slurrying tank after being mixed will be poured into mold box below the Slurrying tank.

Cutting &marshalling of AAC Production line/AAC block

After the base reaches to certain hardness for cutting through static stop curing, the overturning crane on cutting and overturning vehicle (10t) hoists and overturns the base to the cutting dolly and demoulds, which overturns the base 90 degrees. Cutting dolly moves to finish transverse and vertical cutting.
The cut base with side plate will be conveyed by marshalling crane to the steam curing dolly and then pulled into autoclaves to steam curing. China hot sale AAC making plant,autoclaved lightweight block machine,lightweight block plant,clc plant

Steam curing & finished product of AAC Production line/AAC block

The steam curing time in constant pressure is 4 to 10 hours with the steam pressure 1.3Mpa and temperature around 190°C. Finished products after steam curing are dragged out from autoclave by slow moving hoist, and be lifted by crane to the transport vehicles.

Retuning, assembling and oiling on Base (side) plate
After conveying the finished products, the bottom (and side) plate on steam curing dolly with the dolly are lifted to lane for returning.
