We are one of professional manufacturers & supplier of autoclaved aerated concrete (AAC) plants in China, and we can supply complete set of autoclaved aerated concrete plant with 50000, 100000,150000m3 capacity annually (from 166 m3 to 500m3 per day), including plant design, equipments installation, technical instruction, personal training, etc., and also can design and manufacture as per clients' requirement.

aac block production line  design:

1. Plant area is 7500-15000 m2, and we can make design based on your actual area of land.

2. Plant should have raw materials field and finished products field;

3. Plant should have maintenance workshop, test room, warehouse,etc.

Aerated concrete brick (light brick ) is the light and porous building material. It has light weight 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), they could be used industry building and common building, they are more and more popular in the world. In the future,they will replace the Clay brick completely.

aac block production line:

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 with a certain temperature & time, the block would reach certain hardness prepare for cutting

5. Tilting hoister would turn over 90 degree of mould 

6. Then open the mould & separate it from block, take the block with side plate with cutting cart 

7. The block then be cut through the cutter firstly of two vertical sides of block 

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 autoclave

12. Hardening the blocks under certain temperature and pressure 

13. Take finished products out of autoclave 

14. The finished product hoister takes the finished product to stock shield 

15. Packed for loading 

16. The side plate return back by side plate roller

17. Side plate would be organized with open mould

18. Clean the mould and preparing for next pouring 

19. Steel bars processing line for slab production

aac block making machine features:

fire resistance, earthquake resistance, light weight, lesser breakage and saves structural cost by 40%.

 Since 60% of country’s electricity comes from coal based power station, the country has a huge stock of fly ash amounting to 60 million tons annually.
