Product Description
HONGFA Wholesale Block Cutting Machine Concrete Block Making Machine Price
The AAC production process includes raw material preparation, batching and mixing, pouring, precuring, cutting, autoclaving, and packing.
Hongfa establish in 1990,now has 80 AAC production line plant abroad,With our rich experience and advanced technology, we can supply customers with quality AAC block production lines with capacity ranging from 80,000m3 to 400,000m3 per year.
The raw materials of autoclaved aerated concrete are mainly calcareous materials containing calcium oxide (lime/cement), siliceous materials containing silica (fly ash, sand, tailings, other solid wastes, etc.), aluminum powder paste and other additives. Generally, the sand needs to be processed by ball mill, made into slurry. The prepared slurry is stored in the mixing tank. Continuous mixing is required to prevent slurry deposition and ensure stable concentration for easy batching.
THE ADVANTAGES OF AAC:
1. Low density : Can be 325kg /m3
2. Good thermal insulating properties
3. Cost few time to build, saving time
4. Easy to operate , saving labor cost
5. Good performance of preventing fire
6. Good sound-insulation properties
7. Durable , anti-seismic , recyclable

Production Process
Concrete Making Machine for Building Material Making
Raw material preparation
1. Dose and match measured raw materials;
2. After distributing, feed raw material into pouring mixer to make slurry.
Reinforcement processing
3.Automatic circulation system for cage assembly frame
4.Mesh cage anti-corrosion drying room
5.Automatic warp and weft rib full wire strip welding machine
6.Cage assembly frame shuttle
7.Mesh cage rigid connection welding machine
Net cage anti-corrosion spreader
Pouring pre-uperation
9. Through thoroughly mixing, the slurry is poured to mould; ,
10. After pre-curing under a certain temperature and time, the block would reach a certain hardness and prepare for cutting;
Cutting section
11. Tilting hoister would turn over 90 degrees of mould;
12. Then open the mould and separate it from block. And take the block with side plate to the cutting cart;
13. The horizontal cutting machine cuts blocks from both sides.
14. Then the vertical cutting;
Marshalling steaming
15. After cutting, the block is hanged to curing carts with side plate by semi-finished product hoister;
16. Grouping the carts and put them into autoclaves;
17. Curing the blocks under certain temperature and pressure;
18. Carry the finished product out of autoclave by the ferry cart
Finished product packaging
19. The finished product hoister take the finished product to finished blocks area;
20. The side plate return back through side plate roller;
21. Side plate would be organized with open mould for the next circle.
