1, Introduction of AAC Block Manufacturing Line
Areated concrete block (light block) is the light and porous building material. It has light keeping temperature cant burn and other advantages. It can be made into many kinds of bricks for example: 600× 200× 100, 80× 80× 180, 240× 115× 53, 600× 200× 125)
Areated concrete common conception Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3, 600kg/m3, 700kg/m3. It has not the big grain, main use silicon material (for example: Coal ash, sand, stone dust and others ), through making the material small for example sand, they can be used directly if has enough degree of small (for example coal ash. Mixing calcium material lime cement water to a special slop, then add the aluminum dust and the additive. Make the aluminum dust and the special slop have a Chemical reflect. Then produce Hydrogen to make the concrete slop to expanding or swell, foam. Next, put them into the curing room to concreting cutting steaming curing, last, there will become the light brick, the porous rate is 70-80%.
2, Main features of AAC Block Manufacturing Line
1. Light weight, Areated concrete density is usually 400-700kg/m3, (according the market in produce ), same as 1/3 of clay block and 1/5 common concrete. So use the Light block can reduce the weight of the build more, and also reduce the beam of roof and pillar press best. Then you can see, it can save the material and cost, it also fighting shaking.
2...Keeping temperature It has many are porous, the delivery hearting coefficient is 0.9-0.22W/(mk), the same as 1/4 or 1/5 of clay brick, so it is best materials now in the world.

2.Autoclaved Aerated Concrete AAC Block Making Machine Introduction:
Autoclaved Aerated Concrete (AAC) Block -aac block machine , also called Light Block, used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process ofbatching, pouring, cutting, autoclaving, separating and packing to make into the final products. It is new type & environmental construction material and widely used for industry and civil building construction. aac block machine is the most mature technology of production and application in the worldwide nowadays.

3.Advantages of AAC Blocks:
1.Lightweight: Porosity achieve 70% to 85%, volume density is generally 500-900kg/m3, as 1/5 of general concrete brick,the 1/4of clay brick, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building,moreover,prolong building's life.
2.Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 100 mm walls can reach to 4 hours fire resistance, 300mm thick up wall can reach to 9 hours fire resistance.
3.Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 100mm thick wall up to 41 db.
4.Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
5.Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
6.Anti-seismic: The same building structure, improve the two seismic than the brick level.

5.Main Process Flow of AAC Production line/AAC Block Making Machine Line:
1. Raw material: Store the fly-ash (tailings etc), lime and gypsum after milling to the needed fineness (200 mesh)
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 8 hours.
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.
