Material:
Sand
1.Sand is widely used siliceous material in aerated concrete industry . The main function of sand is to provide SiO2.
Fly ash
2.The role of fly ash in AAC is also to provide SiO2.And the Al2O3 in fly ash can give large effect during static stop after the casting process .
Lime
3. Lime is the main calcareous material in the production process. Its main function is to provide calcium oxide, so that it can react with SiO2 and Al2O3 in the siliceous material under hydrothermal conditions to form calcium silicate hydrate, so that the product can gain strength.Finely ground quicklime is used in the production process.
Cement
4.Cement is a hydraulic cementitious material, Portland cement is suitable for AAC.

Introduction of AAC Block Production Line
Raw Material Preparation.
1.Raw materials need to be ground before being processed. In order to meet the fineness requirements of the feed, block materials such as quicklime and natural gypsum need to be crushed.
2.Grinding can give full play to the activity of the material. The ground slurry has better water retention and higher viscosity due to the dissolution of some components , which can make the slurry have proper consistency and liquidity.
Ball Mill:
Main body: Q235B, plate thickness: δ22mm; Large gear material: ZG45#; small gear material: ZG40Cr Liner material: rubber liner; tile body: rolling bearing.
Material Batching and Pouring
1.Measure various raw materials, adjust the temperature and concentration, and feed materials to the mixing equipment in sequence according to the process requirements.
2.The pouring process is one of the unique processes that distinguish aerated concrete from other concretes. The prepared raw materials are stirred to meet the specified time temperature and consistency requirements to obtain slurry, then pour into the mold.
3.Pouring and batching can be controlled separately or centrally, and different degrees of automation can be realized.
Pouring Mixer
Double cross impellers are used to achieve high-speed mixing. The mixing impellers are cast with high-strength hard nickel alloy,
which has high strength and wear resistance.
TStatic Maintenance
1.The poured mold is pushed into the resting room with a conveyor chain for initial gas generation and initial setting. The room temperature is 50-70°C, and the time is 1.5-2 hours.
2.The resting process is mainly to promote the slurry to continue to complete the hardening process, so that the embryo body reaches a certain hardness for cutting.
Mold
The bottom frame of the mold is processed as a whole, and it is assembled and welded by professional tooling. The mold adopts the butterfly spring rocker locking method to ensure that the mold is completely attached to the side plate
The cutting process is to divide and shape the AAC body to meet the appearance and size requirements. The cutting process reflects the characteristics of air-entrained concrete, which is convenient for large-volume molding, flexible and diverse in shape and size, and large-scale mechanized production.
Cutting Machine Group
1.The side cutting machine realizes the automatic advance and retreat of the knife according to the different width requirements of the plate and the block.
2.Horizontal cutting machine adopts full-column wire groove.
3.The vertical cutting machine adopts the frame pendulum hanging cage type.
Autoclaving Curing
The autoclave curing process is to perform high-pressure steam curing on the cut aerated concrete body, and complete the hydrothermal reaction of CaO-SiO2-H2O in the kettle.
Autoclave:
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
Packing
This is the last process of production, including pull out the finished products form kettle, lifting, inspection, packaging and cleaning and oiling of the bottom plate of the trolley.

Successful project
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.
