Introduction of Fly ash AAC Plant
There are four section for Fly ash AAC Plant
1)Weight batching and mixing
The raw materials are transported from storage silos into weigh bins above the batch mixer. Mix water and any slurried material are weighed or volumetrically dosed into the batch mixer
2)Mixing
A low-viscosity water-based slurry, containing fly ash, cement, quicklime and additives, is produced in the mixer. Finely divided aluminium powder is the final raw material added to the mix. Atatal mixing time of 2-4min is typical, but the aluminium powder is dispersed for only 10-20s before the slurry is discharged from the mixer into oiled rectangular steel moulds. Typically, the moulds are .05-0.7 deep and have volume of 3-4m3. The mass of dry raw materials used in a single mix of AAC ranges from1500 to 3000kg, depending on the final density of the product. An AAC mix is normally termed a cake once it has been cast.
3)Cutting
At the first cutting AAC cake horizontally through the three sets of wires. At the first casting stage vertical wires remove excess material from what were the top and bottom relative to the cake rise. Aseond set of reciprocating horizontal wires cuts the cake into a series of slices. Finally, the cake is held stationay while an array of reciprocating horizontal wires cuts down through the cake
4)Autoclaving
Aerated concrete cannot be cured by dry heat alone. This would drive water of hydration from the cellular structure and prevent the formation of calcium silicate hydrates and calcium alumino silicate hydrates. Autoclaveing is essential because the combination of elevated temperatures and moisture ensures that hydrothermal reactions and the rapid formation of semi-crystalline and crystaline reaction products occur.
