Supply Completer Fly Ash Blocks Making Production Line  in AAC Block Production Line project -- Sinoder Brand

AAC (Autoclaved Aerated Concrete) Block Plant was invented in the mid-1920s by the Swedish architect and inventor Johan Axel Eriksson. AAC is one of the major achievements of the 20th century in the field of construction. It is a lightweight, precast building material that simultaneously provides structure, insulation, and fire and mold resistance. AAC Blocks is a unique and excellent type of building materials due to its superb heat, fire and sound resistance. AAC block is lightweight and offers ultimate workability, flexibility and durability.

1. COAL FLY ASH :

The coal fly ash will be sent to the slurry preparing pond by wheel loader to prepare required concentration coal fly ash slurry by adding rated water, which will be pumped into slurry tank to be stored and made.

2. QUICK LIME

The powder will be sent into the lime powder silo for storage and made ready by bucket elevator, after coming into the factory.

3. GYPSUM ASH :

The gypsum in the storage shed will be added into slurry pond according to the required proportion, while preparing slurry.

4. CEMENT :

The cement will be transported into factory by tank truck and directly is pumped into cement silo to be used.

5. ALUMINUM POWDER PASTE :

The purchased aluminum powder paste in the bucket or bag will be stored in its storehouse, When being used, it will be lifted to second floor of the batching building, then measured and added into aluminum mixer to prepare 5% suspending liquid to be used.

6. SCRAPE AND WASTE SLURRY :

The cleaning waste water under the casting machine will be pumped to ball mill to be used as grinding water. The scrape from the cutting machine will be prepared to slurry and pumped into waste slurry tank to be used.

7. BATCHING, MIXING, CASTING:

Coal fly ash will be sent to electronic scale in the batching building by pump at the bottom slurry tank to be measured. When the slurry concentration arrives at batching requirement, the control system will turn off the pump to stop pump slurry. The measured the slurry will be directly discharged into casting mixer.

 

Lime and cement will be sent to electronic scale in the batching building by single screw conveyer at the bottom of their silos. When measuring arrives at the required quantity, they will be sent to casting mixer by screw conveyer.

 

Aluminum powder will be measured by manual, and added into aluminum mixer to prepare suspending liquid one by one for each mould. The finished suspending liquid can be directly added into the casting mixer.

 

The slurry temperature should be arrived at required process temperature before casting. And mould will be moved to the bottom of the casting mixer by ferry car.

8. CUTTING AND GROUPING :

After pre-curing, the green block arrive at the required strength, the crane will take it to the cutting machine section. After removing the mould, the green block will be cut according to the required size.

The green block after cutting will be moved to the curing trolley with the bottom plate by crane in front of autoclave for grouping. The seven trolleys for each autoclave with 14 pieces of green block.

9. AUTOCLAVED AND FINISHED PRODUCT :

The green block after grouping, will be moved into the autoclave by windlass for curing. The whole curing period is approx. 12h, pressure approx.1.2Mpa, temperature approx. 185°C.

 

After curing, the product will be pulled out of autoclave, and be sent to the store yard.

10. THE BOTTOM PLATE RETURNING, COMBINING WITH MOULD AND OILING :

After unloading, the side plate on the trolley will be lifted to returning rail by crane, and be returned to the side of the cutting machine, which will be combined with the mould and sent to mould returning line for cleaning and oiling to be reused.
