What is AAC
AAC is a kind of light cellular silicate products. Main material based on Silicon materials (sand, fly ash,gangue contains silicon) and Calcium(cement and lime),mix with foaming agent(Aluminium powder), a fter batching, mixing, pouring,pre-curing,cutting,steam(autoclaved),and other process,finally, get this light weight concrete products.
Introduction of AAC Block Production Line
2.Processing of raw materials:
Fly ash, sand or limestone is sent into ball mills by vibration feeders and belt conveyor.Then fine powders of flyash,sand or lime are pumped into slurry tank.
Quick lime is sent by vibrating feeder and belt conveyor into jaw crushers to crush. Crushed lime is sent into lime silo by bucket elevator and then is transported into ball mills by screw conveyor. Fined materials are sent into proportion bin by screw conveyor and bucket elevator.
1.Storing and supplying of raw materials of AAC blocks:
All raw materials are carried into factory by trucks, such as Fly ash, sand or lime are gathered in specified raw materials field waiting for use. Sacks of cement and bulk cements stored in cement warehouse. Chemicals and aluminium powder are separately keept in chemical warehouse and aluminium warehours.When used, these raw materials are carried into workshop respectively.
3.Aerated block ingredients,stiring and casting
Flyash (or sand or stone powder )and waste slurrry are measured in measuring tank.After the measuring and mould in their place,slurry stirring begins. Slurry temperature should reach about 40°c.

Raw material processing
1). The cement is bulk cement, which is pneumatically transported to the cement storage bin by a bulk cement truck. The cement storage capacity considered in this design is 90t.
2). After the lime and gypsum are crushed by the jaw crusher by calculation, the elevatorenters the storage bin, is fed by electromagnetic vibration, enters the mill, and the finely mixed ash is transported by the elevator to the ash storage bin for backup.
3). The sand is transported into the slurry storage tank through ball milling and water wet milling into a slurry storage tank, and after the slurry specific gravity required for production is reached, it is pumped to a stirring pouring machine through a slurry pump.
4.Aerated block’s precuring and cutting
1). Ingredients pouring
After the materials are ready, measure them separately, mix and stir with a stirring pouring machine,
add the metered and stirred aluminum powder suspension, stir for 30-45 seconds, and then pour into the mold.
2). Cutting Section
After pouring and foaming, the green body is statically stopped to a certain hardness (about 1.2-2h), that is, cutting is performed, and the green body is lifted to a steaming cart by a marshalling spreader, and then marled into a kettle
3). Autoclave
After cutting the green bodies, they can be marshalled to a certain number by driving and then enter
the autoclave for autoclaving.

Advantages of AAC Block
1. Lightweight:
The aerated concrete dry bulk density generally is 400-800kg/m3, equivalently to clay brick 1/3, normal concrete 1/5, lower than normal light-weight aggregate concrete and hollow brick, hollow clay brick. so, using aerated concrete as wall material can lighten the building self weight, and then reduce the size of building foundation, girder and pillar etc. Structure, save building material and project cost, improve the building shock resistance.
2. Good heat preservation performance:
The aerated concrete inside have abundance tiny air hole, so it have good heat preservation performance, its coefficient of heat conductivity generally is 0.09-0.02W/(m.k), only 1/4-1/5 for clay brick, normal concrete 1/51/10. Usually 20cm thick aerated concrete wall heat preservation performance is correspond to 49cm normal clay brick wall, thus not only save heating and cooling energy, but also improve greatly building plane using coefficient.
3. Processability:
The aerated concrete don't use coarse aggregate, has good processability, can be sawed, digged, drilling and pinning, also can be cohered by suitable binding material, which give favorable condition to building operations.
4. Wide raw material source, high production efficient, low energy consumption
The aerated concrete can be produced by sand, ore slag, fly ash, tailing ore, coal gange and quick lime, cement etc. According to local actual condition to determine variety and process, and can using industrial waste residue greatly. The aerated concrete have high production efficiency, a medium scale AAC plant, annual per capita labor efficiency can reach to 600m3, some high degree automation can reach 900-1000m3, higher than clay brick (180m3) and concrete brick (500-800m3). Its production energy consumption is low, unit product energy consumption is only 50% for same volume clay brick.
Although the industrial production history of aerated concrete in China only has 40 years, its classification already developed non weight bearing block, weight bearing block, heating preservation block, wall and roof boarding, widely used in industrial and civil building, has become a new type rich vitality building material.
Main Raw Material for AAC BlockMain Raw Material for AAC Block

5). Cement: meet standard GB175-92, 32.5R bulk cement.
Material-milling Equipments
1).Crusher: Lime, gypsum, and such kind of bulk material need to be crushed as the first step in AAC Plant.
2). Ball mill: The AAC material must be fully grinded in order to make better reaction. Ball Mill is used widely, it has two types: dry and wet, can be chosen upon requirement.
3). Material Metering Equipments: Computer Control Automatic Metering System is commonly used as measurement of raw materials.
4). Material mixing and casting equipments: Mixer, it’s the slurry mixing machine, also is slurry casting machine.
5). Cutting Machine: the AAC blank is formed after casting and precuring, as the size is too large, it must be cut to achieve the required product size.
6). Autoclave: Autoclave is a device for silicate hydration products to get physical and mechanical properties.
7). Boiler: the boiler supports for the autoclave and preheat furnace and other facilities with heat.
