Professional High Efficiency AAC Block Production Line With ISO
Certificate In Competitive Price
Basic Introduction:
Autoclaved Aerated Concrete (AAC) is a siliceous material (sand,
fly ash and silicon tailings such as waste porcelain clay, stone
processing waste materials, blast furnace slag, etc.) and
calcareous materials (lime, cement) as the main raw material,
mixing fat gas agent (aluminum powder), by ingredients, mixing,
casting, pre-raising, cutting, autoclave, curing process made of
light porous silicate products, because by the hair contains a lot
of gas even after the small pores, hence the name of aerated
concrete.
Technological process:
1. First, dose and match measured raw materials;
2. After distributing, feed raw material into pouring mixer to make
slurry.
3. Through thoroughly mixing, the slurry is poured to mould;,
4. After pre-curing under a certain temperature and time, the block
would reach a certain hardness and prepare for cutting;
5. Tilting hoister would turn over 90 degrees of mould;
6. Then open the mould and separate it from block. And take the
block with side plate to the cutting cart;
7. Firstly, the cutting machine vertical cuts blocks from both
sides.
8. Secondly the horizontal cutting;
9. Finally the vertical cutting;
10. After cutting, the block is hanged to trolley with side plate
by semi-finished product hoister;
11. Organizing the cut blocks and put them into autoclaves;
12. Hardening the blocks under certain temperature and pressure;
13. Carry the finished product out of autoclave;
14. The finished product hoister take the finished product to stock
shield;
15. Packed for loading;
16. The side plate return back through side plate roller;
17. Side plate would be organized with open mould;.
18. Clean the mould and prepare for next pouring;
19. Steel bars processing line for slab production.
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. Miller: 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 materials.
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. Block packing machine.
