AAC Block Machine Production Line

Aerated concrete common conception      
  Common concrete density is usually 1600-2400kg/m3, but Aerated concrete are 500Kg/M3, 600kg/m3, 700kg/m3. It mainly 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, limee foam inside.  Next, put them into the pressured steam room.  Last, there will become the light brick (or say foam block).  The final products has the porous rate is about 70-80%.    

Advantages of AAC Products:        
  A.  Light weight        Aerated concrete density is usually 400-700kg/m3, it is about 1/3 of the clay brick weight and 1/5 common concrete block weight. Using the Light brick can reduce the weight of the build and also reduce the loading of the beam of roof and pillar. You can see, it can save the material and cost, it also fighting against shaking.  

B.   keeping temperature       It has many porous, the heat transition coefficient is 0.9-0.22W/ (mk), it is just about 1/4 or 1/5 of clay brick, so it is the best materials for keep the room temperature now in the world.    

C. environmental protection    There are many kind materials even waste material can produce the AAC products, for example: coal ash, sand, waste mine material, coal stone, stone dust, and other silicon materials.  

D. Save the land and energy      When you produce AAC products it use the energy (or fuel) just 11% of the clay brick Products.    

E.  Plasticity     As it is has more foam  Inside and weight is lighter and not so hard so it is easy to be produced in every kind shape and when it is re-assemble or re-production it will be more suitable for sawing, paring, drilling, and clinch (clench).  

F. Sales Profit:    AAC Products market profit it good then common brick and cement blocks, especially the AAC Board products (Plate shape AAC Products).


Main Equipments in AAC Production Line:

Material-milling Equipments:
          a. Crusher: Lime, gypsum, and such kind of bulk material need to be crushed as the first step in AAC Plant.  

          b. 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.

Material Metering Equipments: Computer Control Automatic Metering System is commonly used as measurement of raw material such as lime powder, cement powder, aluminum powder and material slurry.
Material mixing and casting equipments: Mixer, it's the slurry mixing machine, also is slurry casting machine.
Cutting Machine: the AAC blank is formed after casting and pre-curing, as the size is too large, it must be cut to achieve the required product size.
Autoclave: Autoclave is a device for silicate hydration products to get physical and mechanical properties.
Boiler: the boiler supports for the autoclave and pre-heat furnace and other facilities with heat.
Auxiliary Equipments:
          a. Mould Frame, Mould Bottom and Mould Car, they composed together to form the Casting Mould, which is the main forming equipments in AAC Production Line.

          b. Hardening Car, Ferry Cart and Hangers, they must be equipped as auxiliary equipments in autoclave curing system.

          c. Block Separator. The separator is a special machine whose function is to separator the plaste block into piece,in order to be transfered and used.

          d. Finshed product clamp.

          e. Block packing machine.
