Production Engineering of Light-weight AAC Block (DY)
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

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

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
